The Mercedes-Benz OM605 is a 2.5 L (2,497 cc) inline-five cylinder (R5/I5) double overhead camshaft (DOHC) diesel engine with indirect injection manufactured by Mercedes-Benz between 1993 and 2001. It replaced the single overhead camshaft (SOHC) OM602 engine.

It uses a Bosch electronically controlled inline injection pump (ERE) except in the W124 where it uses a Bosch mechanically governed inline injection pump (Bosch M pump with RSF governor).

It is related to the straight-4 2.0 and 2.2 litre OM604 and the straight-6 3.0 litre OM606 engines.
