A mortar carrier, also known as a self-propelled mortar, is a self-propelled artillery vehicle carrying a mortar as its primary weapon. Mortar carriers cannot be fired while on the move and some must be dismounted to fire.

In U.S. Army doctrine, mortar carriers are to provide close and immediate indirect fire support for maneuver units while allowing for rapid displacement and quick reaction to the tactical situation. The ability to relocate not only allows fire support to be provided where it is needed faster but also allows these units to avoid counter-battery fire.
