'''Power Stroke''', also known as '''Powerstroke''', is the name used by a family of diesel engines for trucks produced by [[Ford Motor Company]] and [[Navistar International]] (until 2010) for Ford products since 1994. Along with its use in the [[Ford F-Series]] (including the [[Ford Super Duty]] trucks), applications include the [[Ford E-Series]], [[Ford Excursion]], and [[Ford LCF]] commercial truck. The name was also used for a diesel engine used in South American production of the [[Ford Ranger]].

From 1994, the Power Stroke engine family existed as a re-branding of engines produced by Navistar International, sharing engines with its medium-duty truck lines. Since the 2011 introduction of the 6.7&nbsp;L Power Stroke V8, Ford has designed and produced its own diesel engines. During its production, the Power Stroke engine range has been marketed against large-block V8 (and V10) gasoline engines along with the General Motors [[Duramax V8 engine|Duramax V8]] and the Dodge [[Cummins B Series engine|Cummins B-Series inline-six]].
