The Renault R31 (also known as the Lotus Renault R31) was a Formula One racing car designed by Lotus Renault GP for the 2011 Formula One season. The chassis was designed by James Allison, Naoki Tokunaga, Tim Densham and Dirk de Beer with Rob White leading the engine design. The car was driven by Vitaly Petrov and Nick Heidfeld, who was replaced mid-season by Bruno Senna.

This was the first Enstone-based Formula One car supplied with Pirelli tyres since the Benetton B191 in 1991.
