The Nissan Leaf , stylized as "LEAF," is a battery-electric powered compact car manufactured by Nissan, produced since 2010 across two generations. It has been offered exclusively as a 5-door hatchback. The term "LEAF" serves as a backronym to leading environmentally-friendly affordable family car.

A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that exclusively uses chemical energy stored in rechargeable battery packs, with no secondary source of propulsion. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. They derive all power from battery packs and thus have no internal combustion engine, fuel cell, or fuel tank. BEVs include – but are not limited to – motorcycles, bicycles, scooters, skateboards, railcars, watercraft, forklifts, buses, trucks, and cars.
