HMAS Waterhen is a Royal Australian Navy (RAN) base located in Waverton on Sydney's lower north shore, within Sydney Harbour, in New South Wales, Australia. Constructed on the site of a quarry used to expand Garden Island in the 1930s, the location was used during World War II as a boom net maintenance and storage area. In 1962, the area was commissioned as a base of the RAN, and became home to the RAN's mine warfare forces. Waterhen was the first small-ship base established by the RAN, and from 1969 to 1979 was also responsible for the RAN's patrol boat forces.
