A remote controlled weapon station (RCWS), remotely operated weapon system (ROWS), or remote weapon system (RWS), is a remotely operated light or medium-caliber weapon system, often equipped with a fire-control system, that can be installed on a ground combat vehicle or sea- and air-based combat platform.

Such equipment is used on modern military vehicles, as it allows a gunner to remain in the relative protection of the vehicle. It may be retrofitted onto existing vehicles, for example, the CROWS system is being fitted to American Humvees.
