1981 Caesars Palace Grand Prix

The 1981 Caesars Palace Grand Prix was a Formula One motor race held on October 17, 1981, in Las Vegas, Nevada, United States. It was the fifteenth and final race of the 1981 Formula One World Championship.

The 75-lap race was won by Australian driver Alan Jones, driving a Williams-Ford, with Frenchman Alain Prost second in a Renault and Italian Bruno Giacomelli third in an Alfa Romeo. Brazilian Nelson Piquet finished fifth in his Brabham-Ford to take the Drivers' Championship by one point from Jones's Argentine teammate, Carlos Reutemann, who finished eighth having started from pole position.

This was the last F1 race to be won by an Australian driver for 28 years, until Mark Webber won the 2009 German Grand Prix.
