The 1984 Dallas Grand Prix was a Formula One motor race held on July 8, 1984 at Fair Park in Dallas, Texas. It was the only running of the Dallas Grand Prix as a Formula One race, and the ninth race of the 1984 Formula One World Championship.

The race was held in very hot weather on a disintegrating track, and was won by Finnish driver Keke Rosberg, driving a Williams-Honda, with Frenchman René Arnoux second in a Ferrari and Italian Elio de Angelis third in a Lotus-Renault. Englishman Nigel Mansell took pole position in the other Lotus-Renault and led the first half of the race, before suffering a gearbox failure at the very end and collapsing from exhaustion while trying to push his car over the finish line.
