The 1992 Monaco Grand Prix was a Formula One motor race held on 31 May 1992 at the Circuit de Monaco. It was the sixth race of the 1992 Formula One World Championship.

The race was won by Ayrton Senna, driving a McLaren-Honda. Drivers' Championship leader Nigel Mansell took pole position in his Williams-Renault and led until lap 71, when he suspected he had a puncture and made a pit stop for new tyres. He emerged behind Senna, closed up to the Brazilian and tried to find a way past but without success, Senna holding on to win by 0.2 seconds. It was Senna's fifth Monaco Grand Prix win, equalling the record set by Graham Hill.

Mansell's teammate Riccardo Patrese was third, half a minute behind.
