The Leyton House CG901 was a Formula One racing car designed by Adrian Newey for the 1990 Formula One World Championship. Five chassis were built and were powered by the Judd EV 3.5 litre V8 engine. Chassis 001 was subsequently modified mid-season to accommodate the Ilmor 2175A engine the team used in 1991. The drivers for 1990 were the highly rated Ivan Capelli and Maurício Gugelmin. The CG in the name stood for Cesare Gariboldi, a March Leyton team manager who was killed in a road accident in 1989.

The performance of the CG901 was very poor before the introduction of the B specification car at the French Grand Prix of 1990. In both France and Britain both Capelli and Gugelmin showed dominant form bewildering their much better-funded rivals.
