The Nissan A series of internal combustion gasoline engines have been used in Datsun, Nissan and Premier brand vehicles. Displacements of this four-stroke engine family ranged from 1.0-liter to 1.5-liter and have been produced from 1967 till 2009. It is a small-displacement four-cylinder straight engine. It uses a lightweight cast iron block and an aluminum cylinder head, with overhead valves actuated by pushrods.

The Nissan A engine design is a refined, quiet and durable gasoline engine. It appears to be a modern replacement of the earlier iron-headed Nissan C and Nissan E engines and is of similar dimensions. The 1960s E series was an all-new design from newly acquired Aichi Kokuki, and integrated Nissan's improvements to the BMC B-Series engine design of the 1950s (Nissan was a licensee of Austin Motor Company technology), mainly comprising changing the camshaft from the left side to the right side so removing the intrusion of the pushrods from the porting allowing for eight individual ports instead of the original five, and moving the oil pump from the rear of the camshaft to the right side of the block. As production continued, 1974 and newer A-series engines had different block castings, with relocated motor mount bosses.
