The 1983 Monaco Grand Prix was a Formula One motor race held at Monaco on 15 May 1983. It was the fifth race of the 1983 Formula One World Championship. The 76-lap race was won by Finnish driver Keke Rosberg, driving a Williams-Ford (the last victory of Williams in Monaco until 2003 with Juan Pablo Montoya), with Brazilian Nelson Piquet second in a Brabham-BMW and Frenchman Alain Prost third in a Renault. This was only time that both works McLaren cars failed to qualify for a race.
Thirty years later, Rosberg's son Nico won the 2013 race, making them the first father and son to win in the principality.
