The Cheonghaejin-class ASR (Hangul: 청해진급 잠수함 구조함; Hanja: 淸海鎭級潛水艦救助艦) is a submarine rescue ship class of the Republic of Korea Navy. Only one ship has been built in her class, ROKS Cheonghaejin (ASR 21), in 1995. Its operations include rescuing trapped sailors in submarines, naval operation support for submarines, underwater research and mapping support, and recovery of sunk vessels. It is equipped with a deep submergence rescue vehicle (DSRV) that operates up to 500 metres (1,600 ft), and a rescue chamber that holds up to nine people.

Once all nine Son Wonil-class submarines are delivered to the Republic of Korea Navy, another ASR ship of the same class is planned to be built.
