The Lotus E20 was the car designed by Lotus F1 for the 2012 Formula One season. It was driven by Kimi Räikkönen and Romain Grosjean, with Jérôme d'Ambrosio replacing Grosjean at the Italian Grand Prix. The car was powered by Renault. The car is the first to be designed by the Lotus F1 team since their renaming from Renault. The name "E20" comes from the fact the car is the twentieth car to be designed at Enstone.

The E20 led the team to 4th in the World Constructors' Championship, and helped Kimi Räikkönen to the first win of his comeback year, at the 2012 Abu Dhabi Grand Prix.
