A '''V20''' is an [[internal combustion engine]] in [[V engine|V]] configuration, having 20 [[cylinder (engine)|cylinder]]s. 

Engines of this number of cylinders are not common, but this configuration was used in some large [[diesel engine]]s. For example, the [[1960s]] vintage [[General Motors Electro-Motive Division]] [[EMD SD45]] [[railroad]] [[locomotive]] was fitted with a 20-cylinder EMD 645E3 engine. 

The engine name is based on the [[engine displacement|displacement]] of each cylinder in [[cubic inch]]es. In this case 645 inch&sup3; (10.6 [[litre|L]]) for each of 20 cylinders - a total of 211 L. Power output is 3,600 [[horsepower]] (2.7 [[megawatt|MW]]).

V20 diesel engines have also been used in marine applications:  Mercedes-Benz has produced one such engine.
