The SR engine is a series of 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) straight-four, four-stroke gasoline engines manufactured by Nissan. It has an aluminium head and block with steel sleeves and has a DOHC 4-valve design, with variable valve timing on select models. It was added to a new engine family name PLASMA (Powerful ＆ Economic, Lightweight, Accurate, Silent, Mighty, Advanced).

The engine was used in many small to medium Nissan vehicles, including high-performance turbocharged variants. It was designed by Nissan as a replacement of the earlier CA series of engines, and was replaced by the QR and MR series of engines. Power outputs are shown under JIS Net PS or ECE Net kilowatts unless otherwise indicated.
