The Ligier JS P2 is a racing car designed and built by French manufacturer Onroak Automotive and named in partnership with French former racing driver Guy Ligier. Designed for the Le Mans Prototype 2 (LMP2) regulations, it is intended as a second option to Onroak's Morgan LMP2 that has been competing since 2012. As well as being the first closed-cockpit car offered by Onroak, it is also the first car they designed entirely in-house. The JS P2 debuted at the 2014 24 Hours of Le Mans, and has been campaigned in the FIA World Endurance Championship, European Le Mans Series, Asian Le Mans Series and IMSA WeatherTech SportsCar Championship.

Ligier Automotive, formerly Onroak Automotive, is a French company which designs, manufacturers, and sells racing cars, specifically sports prototypes for various international series. Onroak was founded in 2012 by Jacques Nicolet who split the design, manufacturing, and sales divisions of his OAK Racing team into an independent company. Onroak has since formed an agreement with Philippe Ligier to develop new cars under the Ligier title. On 31 December 2018, it was announced that Onroak Automotive would be rebranded to Ligier Automotive as part of a rebranding and reorganization of Everspeed's automotive assets.
