HMAS Cook (GOR 291/A 219), named after Captain James Cook, was an oceanographic research vessel of the Royal Australian Navy (RAN).
Design work for a dedicated oceanographic research vessel to replace the converted frigate began in the late 1960s. The ship was ordered in 1973. on 30 September 1974, launched on 27 August 1977 and commissioned into the RAN on 28 January 1980. In 2022, both vessels were dismantled even though the conversion had made progress earlier.
