The Nissan C-series was an inline-four automobile engine produced in the 1950s and into the 1960s. It displaced 1.0 L (988 cc) and produced 37 hp (27.6 kW) and 47.7 to 49 lb·ft (64.7 to 66.4 Nm). It was a pushrod engine and used single or dual-26 mm carburetors.

The C engine was derived from the 1.5 L Nissan 1H (1489 cc) engine, itself being a licensed built version of the 1.5 BMC B-series engine that featured a 73 mm (2.87 in) bore and 89 mm (3.50 in) stroke. To create the C engine, Nissan under the advice of American engineer Donald Stone (formerly of Willys-Overland) followed his suggestion of de-stroking the 1.5 engine from 89 to 59 mm (3.50 to 2.32 in), with the resulting C1 engine being called the "Stone engine" in his honor.^[1]^[2] When it was later increased to 1.2 L via an increased stroke from 59 to 71 mm (2.32 to 2.80 in), it was called the Nissan E engine.^[3]

The Nissan C engine would go on to be directly replaced by the Nissan A engine in the 1967 Nissan Sunny B10, whose 1-litre A10 unit shared the same displacement from the same 73 mm × 59 mm (2.87 in × 2.32 in) bore and stroke as the C engine.
