猎潜舰（英语：Submarine chaser），又称驱潜舰，是海军小型反潜作战船只。主要装备是主动声纳、深水炸弹、反潜火箭等。也会携带机枪与舰炮。特别是二战时期的猎潜舰往往要顾及与潜艇的甲板炮展开炮战。

二战时期，美国海军的猎潜舰型号以PC开头，意指“近岸巡逻船”（Patrol, Coastal）。大量装备给美国海岸警卫队，护卫离开美国港口的商船不被德国海军的U型潜艇伏击。太平洋战争中，美国猎潜舰用于登陆战、联络（courier）与护航。

日本海军在二战时有约250艘猎潜舰，主要是200艘1式辅助猎潜舰

A submarine chaser is a small and fast naval vessel, specifically intended for anti-submarine warfare. Although similar vessels were designed and used by many nations, this designation was most famously used by ships built by the US. Many of the US World War I sub-chasers found their way to friendly powers by way of Lend-Lease in World War II.
