A crosshead is a mechanism used in most steam locomotives to eliminate sideways pressure on the piston.

Crossheads in a steam locomotive can be mounted either to one guide mounted above the crosshead or to two, one above and one below (called an alligator crosshead since it has two "jaws"). The former was preferred in many modern locomotives.
