The 2023 FIA Formula One World Championship was a motor racing championship for Formula One cars, which was the 74th running of the Formula One World Championship. It was recognised by the Fédération Internationale de l'Automobile (FIA) as the highest class of competition for open-wheel racing cars. The championship was contested over twenty-two Grands Prix, which were held around the world. It began in March and ended in November. Drivers and teams competed for the titles of World Drivers' Champion and World Constructors' Champion, respectively. Max Verstappen won his third consecutive Drivers' Championship title at the Qatar Grand Prix, while his team, Red Bull Racing achieved their sixth Constructors' Championship title, the second consecutively, at the preceding Japanese Grand Prix.

Red Bull Racing locked out the front row for the season opening Bahrain Grand Prix. Max Verstappen led nearly all the race comfortably, winning by eleven seconds ahead of his teammate Sergio Pérez.

In the Saudi Arabian Grand Prix, Pérez took pole position in qualifying. Pérez dropped to second position in the first lap to Alonso, but regained first on lap four. Verstappen, starting fifteenth on the grid, reached second by lap 25, and remained there for the rest of the race. Verstappen also recorded the fastest lap.

At the Australian Grand Prix, Verstappen took pole position in qualifying with Pérez starting from the pit lane. At the start of the race, Verstappen was overtaken by Russell and Hamilton. He regained the lead by lap 12 and led the race comfortably. Verstappen won the race, followed by Hamilton and then Alonso. The Grand Prix broke the record for most red flags, with three.

The Azerbaijan Grand Prix saw the season's first sprint event. Leclerc secured pole position ahead of Verstappen and Pérez. Additionally, Leclerc managed to secure pole position for the sprint ahead of Pérez and Verstappen. Sprint polesitter Leclerc got a good start off the line to take the lead of the sprint until Pérez had the opportunity to pass Leclerc on the main straight courtesy of the DRS; he kept the lead until the end of the sprint. In the race, polesitter Leclerc led the race until lap four. The DRS was enabled on lap three, with Verstappen utilising it to pass Leclerc into the first corner on the following lap. Pérez repeated the same move on lap six to take second place. Pérez took his second Azerbaijan Grand Prix victory.

At the Miami Grand Prix, Pérez secured pole position ahead of Alonso and Sainz; Verstappen started ninth after he was unable to set a time, compounded by Leclerc crashing out during the final stages of Q3 and bringing out a red flag. Verstappen made up several positions during the race and secured his second Miami Grand Prix victory.

Verstappen secured pole position at the Monaco Grand Prix, ahead of Alonso. The race was dry to start with but rain soon arrived leading to the first runners to switch to the intermediate tyres on lap 51. Verstappen secured his second Monaco Grand Prix victory, with Alonso finishing second, his best result of the season.

Verstappen secured pole position once again at the Spanish Grand Prix and cruised to a fifth victory of the season. He led every lap and took the fastest lap of the race. Hamilton finished second ahead of teammate Russell in third, who took his first podium of the season. The double podium for the team moved Mercedes to second above Aston Martin.

At the Canadian Grand Prix, Verstappen continued to dominate, securing pole position in rainy conditions ahead of the Haas of Nico Hülkenberg. But Hülkenberg was demoted to fifth following a penalty. Verstappen went on to win Red Bull Racing's 100th victory in Formula One ahead of Alonso and Hamilton. Verstappen's 41st victory moved him to joint 5th on the all-time list, tied with Ayrton Senna.

Verstappen also took pole at the Austrian Grand Prix, both for Sunday's Grand Prix and for Saturday's sprint. Verstappen fought with teammate Pérez on the opening lap of the sprint race, with Pérez appearing to push Verstappen onto the grass on the run up to turn 3. Verstappen retained the lead though, and led every lap to take victory. In the race, Leclerc became the first driver since Pérez at the Miami Grand Prix to lead a lap other than Verstappen, who quickly passed Leclerc to regain the lead. Verstappen took his fifth consecutive victory. A number of drivers fell foul of track limits penalties over the weekend, with 47 lap times being deleted in qualifying alone. During the race, the FIA reported that there were "well over 1,200 instances where a car was reported as potentially leaving the track", and a number of drivers including Lewis Hamilton and Carlos Sainz were given time penalties for multiple breaches.

The British Grand Prix saw a remarked improvement from McLaren, as Lando Norris and Oscar Piastri qualified second and third, respectively. Verstappen took his fifth consecutive pole position, whilst Pérez qualified 16th, failing to make it into Q3 for the fifth consecutive race. Norris made the most of a good start and overtook Verstappen into the first corner. Verstappen re-passed Norris on lap 5 and held on to take his sixth consecutive Grand Prix victory, whilst Norris recorded his best finish of the season finishing second. Hamilton made the most of a safety car to recover the Haas of Kevin Magnussen to jump Piastri and finish in third place, his 14th podium at his home race. The race saw Red Bull Racing equal McLaren's record for the most consecutive victories with eleven.

Hamilton took pole position at the Hungarian Grand Prix. It marked his ninth pole position in Hungary, a record for most poles at a single circuit. Hamilton lost out at the start to Verstappen, and was passed by the two McLarens. He managed to repass Piastri late in the race and finished fourth. Verstappen won to become the fifth driver to win seven races consecutively. Norris continued McLaren's resurgence, and took second. Pérez finished third, having started ninth. Verstappen's win also meant that Red Bull Racing set a new record for most consecutive victories for a constructor with twelve.

The Belgian Grand Prix saw the return of the sprint format, with Verstappen taking pole position in both the Grand Prix and sprint race. He was given a five-place grid penalty for the Grand Prix for exceeding the allocated number of gearboxes, so Charles Leclerc was promoted to pole. In the sprint, Verstappen took the victory, having had to pass Piastri, who came home second. In the race, Pérez took the lead off Leclerc on lap 1. Verstappen took the lead of the race on lap 17, passing Pérez on the Kemmel straight. Verstappen then strolled to his eighth consecutive Grand Prix victory.

At the Dutch Grand Prix, Daniel Ricciardo suffered an accident in the second free practice session while trying to avoid the McLaren of Piastri who had crashed earlier. As a result of the crash, Ricciardo suffered a broken metacarpal bone, which led to him withdrawing from the weekend, being replaced by Red Bull Junior Team driver Liam Lawson. Verstappen took pole for the third year running in Zandvoort. Rain fell on the first lap, which saw drivers pit for inters in the early stages. As a result of the early change in tyres, Pérez led by lap 5. Verstappen undercut Pérez on the change back to dry-weather tyres on lap 13. From there, he kept the lead for the rest of the race. More rain fell in the closing stages, with multiple drivers being caught out by the tricky conditions at turn 1. Zhou aquaplaned and crashed heavily into the barrier at turn 1, which brought out the red flag. At the restart, Norris and Russell collided, with the latter suffering a puncture. Verstappen led home Alonso, to equal Sebastian Vettel's record of nine consecutive race victories. Gasly took his first podium since the 2021 Azerbaijan Grand Prix, after Pérez was given a five-second time penalty for speeding in the pit lane. Lawson finished 13th on debut.

At the Italian Grand Prix, polesitter Carlos Sainz Jr. mounted a successful defense against a charging Max Verstappen for the lead, but he made a mistake on lap 15, allowing Verstappen into the lead and kept the lead until the end of the race, winning his second consecutive Italian Grand Prix.

Sainz made it back-to-back pole positions at the Singapore Grand Prix. Red Bull Racing struggled all weekend, with both Verstappen and Pérez lining up eleventh and thirteenth, respectively. Sainz held the lead at the start, as Leclerc passed Russell at turn 1. A safety car was brought out after Logan Sargeant crashed his Williams, resulting in most of the cars pitting. Leclerc had to be held longer in the pits to allow other cars to pass, seeing him drop to fifth. Sainz would hold off the pressure from both Russell and Norris to take his second Formula One victory. Sainz became the only non-Red Bull Racing driver to win a Grand Prix in 2023, since the 2022 São Paulo Grand Prix, to end Verstappen's run of ten consecutive wins since the Miami Grand Prix and Red Bull Racing's streak of fifteen wins since the 2022 Abu Dhabi Grand Prix.

Verstappen returned to pole at Suzuka for the Japanese Grand Prix. Verstappen cruised to his 13th win of the season, with Norris finishing second, and Piastri scoring his maiden Grand Prix podium. Verstappen's win saw Red Bull Racing clinch the World Constructors' Championship for this season, the team's sixth title overall, and the second title in a row.

The Qatar Grand Prix saw an opportunity for Verstappen to win the title by finishing sixth in the sprint. Verstappen took pole position for the race, while Oscar Piastri reigned for the sprint pole. Piastri battled with George Russel and went on to win his first race as McLaren's first sprint victory ahead of Verstappen and Norris. Verstappen achieved his third consecutive Drivers' Championship. The race was dominated by Verstappen in extremely hot weather, which caught out numerous drivers, including Logan Sargeant, who chose to retire early, Esteban Ocon, who vomited in his car twice but managed to finish the race in seventh, and Lance Stroll, who stated he briefly passed out and experienced blurry vision. Ultimately, Piastri and Norris rounded off the podium once more.

The United States Grand Prix marked back-to-back sprint events, with Verstappen qualifying on pole for the sprint and winning comfortably ahead of Hamilton and Leclerc. Despite brake issues, Max Verstappen won the race, his fifteenth victory in the season. However, post-race scrutineering determined that Hamilton and Leclerc's skid blocks were excessively worn, disqualifying them; the resulting place promotions for the drivers below them gave Logan Sargeant his first career point, at his home race.

Charles Leclerc took his fourth pole position at the Mexico City Grand Prix. Verstappen took the lead at the start, while teammate Pérez collided with Leclerc at turn 1, ending his race. A red flag was brought out on lap 34 to repair the barriers at turn 9 where Magnussen earlier crashed his Haas heavily. Verstappen held onto the lead at the restart and would go on to take his 16th win of the season, breaking his record for the most wins in a season.

The São Paulo Grand Prix saw the final sprint of the season. Norris took pole for the sprint race with Verstappen winning comfortably ahead of Norris and Pérez. Verstappen qualified on pole for the Grand Prix. Leclerc crashed on the formation lap due to a hydraulic failure, and with that did not start the race. At the start, Verstappen held onto the lead ahead Norris and Hamilton, whilst at the back, the Williams of Alexander Albon collided with both Haas cars, crashing into the barriers at turn 1 along with Magnussen. This resulted in a red flag. Verstappen and Norris held their position at the restart, whilst Alonso passed Hamilton for third place. Norris was able to briefly challenge Verstappen for the lead, but Verstappen pulled away. He led the rest of the race comfortably, taking his 17th win of the season ahead of Norris. Alonso and Pérez fought intensely in the closing stages, and Alonso took his first podium in six races to finish third. He beat Pérez by 0.053 seconds.

The Las Vegas Grand Prix marked a return to the location after 41 years. Early runs on track in first practice were curtailed when Carlos Sainz Jr.'s car struck a loose metal cover, severely damaging his car. He had to take a new engine component, resulting in a ten-place grid penalty for the Saturday night race. Charles Leclerc took pole position ahead of teammate Sainz and Verstappen, who would eventually win the race ahead of Leclerc and Sergio Pérez. The leader of the race changed hands multiple times; while Verstappen led a majority of the race, Leclerc and Pérez squabbled for first place on multiple occasions. Leclerc would pass Pérez for second on the final lap. Despite losing the position at the end, Pérez secured second place in the Drivers' Championship, and Verstappen set another record for most races won by a single constructor in a season.

The season came to a close with the Abu Dhabi Grand Prix a week later. During the first practice session, nine teams fielded alternate drivers who had not raced in more than two Grands Prix, as required by the Formula One regulations. All three qualification sessions were topped by Max Verstappen, who would take the pole position ahead of Charles Leclerc and Oscar Piastri. Verstappen led a majority of the Grand Prix, excluding a moment between laps 17 to 22 where Leclerc and Yuki Tsunoda led the race momentarily. A penalty for Sergio Pérez for contact with Lando Norris and Carlos Sainz Jr. being listed in eighteenth, along with both their drivers securing points with George Russell's third and Lewis Hamilton's ninth-place finishes, allowed Mercedes to slip to second place ahead of Ferrari by three points.
