A stroke is a single action of certain engines.
The stroke length is determined by the cranks on the crankshaft. Stroke can also refer to the distance the piston travels; for example, the phrase "This engine has a 100mm stroke" means that on each stroke, the piston travels 100mm.
In a pistonless rotary engine, the term is applied to the corresponding rotor movement, see top dead centre.
