The Porsche 919 Hybrid is a Le Mans Prototype 1 (LMP1) dual hybrid racing car built and used by Porsche in the 2014, 2015, 2016 and 2017 seasons of the FIA World Endurance Championship. It has a two-litre (120 cu in) 90-degree V4 mid-mounted mono-turbocharged petrol engine that produces 500 hp (370 kW) and acts as a chassis load-bearing member – and two separate energy-recovery hybrid systems to recover thermal energy from exhaust gases and convert kinetic energy into electrical energy under braking for storage into lithium-ion battery packs. In accordance with the 2014 regulations, the vehicle was placed in the 6 MJ (1.7 kWh) class.

On 4 March 2014, the 919 Hybrid was shown to the press for the first time during the Geneva Motor Show. Porsche supplied two cars, driven by six drivers, for the season. Romain Dumas, Neel Jani, and Marc Lieb won three pole positions and the season-ending 6 Hours of São Paulo as Timo Bernhard, Brendon Hartley and Mark Webber helped the team to finish third in the World Manufacturers' Championship. In 2015, the car was further developed and was categorized into the 8 MJ (2.2 kWh) category. Bernhard, Hartley, and Webber won four out of eight races to claim the 2015 World Endurance Drivers' Championship and the World Manufacturers' Championship. Earl Bamber, Nico Hülkenberg and Nick Tandy won the 6 Hours of Spa-Francorchamps and 24 Hours of Le Mans, driving a third 919 Hybrid.

In 2016 Dumas, Jani, and Lieb won the 6 Hours of Silverstone and the 24 Hours of Le Mans with the car after further development. Consistent performances from the trio won them the 2016 World Endurance Drivers' Championship and the team's second. Although Bernhard, Hartley, and Webber had reliability issues in the season's first three races, the trio won four of the six remaining rounds to help Porsche win its second consecutive World Manufacturers' Championship. The next year, 2017, Tandy and former Audi LMP1 driver André Lotterer joined Jani in place of Dumas and Lieb, and Bamber teamed up with Bernhard and Hartley, replacing the retired Webber. Porsche finished on the podium in the first two rounds. Bamber, Bernhard, and Hartley recovered from a 13-lap deficit to win the 24 Hours of Le Mans and three more races for Porsche's third consecutive World Drivers' and Manufacturers' Championships at the season's penultimate round, the 2017 6 Hours of Shanghai. After 2017, the 919 Hybrid project was discontinued as Porsche entered Formula E. An evolution of the car, called the 919 Evo, was demonstrated in 2018, setting multiple lap records.
