The Mitsubishi KE engine is a range of engines produced by Mitsubishi Motors during the 1960s and early 1970s. They were extensively used in the various Colt-branded vehicles the company produced from 1963.

The engines were overhead valve iron-blocks, some for petrol and some for gasoline use. The first digit after the KE denotes the number of cylinders, straight-4s becoming KE4 and six-cylinder versions such as the single overhead camshaft 2.0 L straight-6 which was developed in 1964 for the new Mitsubishi Debonair flagship sedan, receiving the KE6 prefix. The last digit is simply a serial, denoting which number engine it is. Some of these engines, such as the two-liter KE42, were further developed into overhead-cam engines and were named Astron.
