The BMW M10 is a SOHC inline-4 petrol engine which was produced by BMW from 1962-1988. It was the company's first four-cylinder engine since the BMW 309 ended production in 1936 and was introduced in the New Class sedans.

The M10 was used in many BMW models, with over 3.5 million being produced during its 26 year production run.^[1]

The turbocharged BMW M12 engine— used in the Formula One racing— was based on the M10 engine block and produced up to 1,400 PS (1,030 kW) in qualifying trim.^{[citation needed]}

Following the introduction of the BMW M40 engine in 1987, the M10 began to be phased out.
