The Honda P engine is an inline three-cylinder gasoline engine first designed for use in Honda kei cars. The P engine was first used in the fourth generation Honda Life, as a successor to the Honda E07A engine. The P engine series was initially produced in only one displacement variant: 658 cc, either naturally aspirated or turbocharged. A turbocharged one-litre version, the P10A, has since been developed. The smaller version was discontinued in December 2013, when it was replaced by the new S07 series engine, but the P10A continues to be built in Thailand.

The Honda Life is an automobile nameplate that was used on various kei car/city cars produced by Honda: passenger cars, microvans, and kei trucks. The first series of the nameplate was built between 1971 and 1974, with the nameplate revived in 1997 and used until 2014. The Japanese-market Life has rarely been marketed outside Japan.
