The Ligier JS29 was a Formula One car designed by Michel Têtu and Michel Beaujon for the Ligier team for use in the 1987 season. It was originally developed for use with an Alfa Romeo turbo power plant but prior to the start of the season, Ligier lost the use of the engine. The car had to be re-designed around a Megatron Straight 4 turbo engine. Redesignated the JS29B, it scored a single point during the season when driver René Arnoux finished 6th in the Belgian Grand Prix. Later in the season, the car was further refined to a JS29C specification.
