The Nissan C-series was an inline-four automobile engine produced in the 1950s and into the 1960s. It displaced {{cvt|988|cc|L|order=flip|1}} and produced {{cvt|37|hp|kW}} and {{cvt|47.7|to|49|lbft|Nm}}. It was a pushrod engine and used single or dual-26 mm carburetors.

The C engine was derived from the {{cvt|1489|cc|L|order=flip|1}} Nissan 1H engine, itself being a licensed built version of the 1.5 BMC B-series engine that featured a {{cvt|73|mm|in|2}} bore and {{cvt|89|mm|in|2}} 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 {{cvt|89|to|59|mm|in|2}}, with the resulting C1 engine being called the "Stone engine" in his honor.{{cite book |last=Halberstam |first=David |title=The Reckoning |date=2012 |publisher=Open Road Integrated Media |location=New York |isbn=978-1453286104}}{{page needed|date=February 2025}}{{cite book |title=Britain & Japan : biographical portraits.

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 {{cvt|73|x|59|mm|in|2}} bore and stroke as the C engine.
