HMAS Rankin is the sixth and final submarine of the Collins class, which are operated by the Royal Australian Navy (RAN). Named for Lieutenant Commander Robert William Rankin, the boat was laid down in 1995, and commissioned into the RAN in March 2003, following major delays.

Early in her career, Rankin was the subject of a documentary series and a coffee table book. She was the first submarine since 1987 to be awarded the Gloucester Cup.
