The Detroit Diesel Series 53 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel as a more compact alternative to the older Series 71 for medium and heavy duty trucks. The number 53 refers to the nominal swept displacement per cylinder in cubic inches.

Inline models included two, three, and four cylinders, and the V-types six and eight cylinders.
