HMS Bonaventure was an Astraea-class second class cruiser of the Royal Navy, ordered as part of the eight-ship Astraea class under the Naval Defence Act of 1889.
Bonaventure served in the Pacific Squadron, including service in the 3rd China War, under command of Captain Robert Montgomerie RN.
She then went to Haulbowline Dockyard, Cork, Ireland to be converted into a depot ship for submarines.
This work was completed in April 1907 and she continued to serve during the First World War as a submarine depot ship.
She was sold on 12 April 1920 to the Forth Ship Breaking Company, Bo'ness.
