The MAN B&W K108ME-C is a low speed two-stroke turbocharged diesel engine for marine engineering applications. It is designed by the Danish department of the German diesel engine supplier: MAN Diesel SE, the former MAN B&W Diesel group, and part of the larger MAN SE.

If the largest version is ever built, it will be the most powerful piston engine, with more than 136,000 brake horsepower (101,415 kW) in Mk-9 version. The cylinder bore of the internal combustion engine will be 1,080 millimetres (42.5 in). It will be used in new container ships of more than 10,000 twenty-foot equivalent unit (TEU) in order to achieve around 25 knots (46 km/h; 29 mph) cruising speed. The thermodynamic efficiency of the engine will surpass 50%.
