The Mitsubishi 4M4 engine is a range of four-cylinder diesel engines from Mitsubishi Motors, first introduced in the second generation of their Montero/Pajero/Shogun SUVs. They superseded the previous 4D5 engine family, although they did not replace them.

Originally available only as a 2.8 L intercooled turbo, detail improvements in 1996 and a larger 3.2 L option in 1999 served to improve power, torque, fuel economy and emissions.
