Admiral Sir Charles Howe Fremantle GCB (1 June 1800 – 25 May 1869) was a British Royal Navy officer.

[5][6][7][8] In August 1826 Fremantle was promoted to captain and in 1828 took command of the 26-gun frigate Challenger,[1] and sent to claim the west coast of Australia for the United Kingdom.

Challenger was dispatched by the Admiralty from the Cape of Good Hope on 20 March 1829,[9] anchored in Cockburn Sound on 27 April and landed on Garden Island the next day.

"[9][10][11] The appointed Lieutenant Governor James Stirling arrived in Cockburn Sound, Western Australia, on 2 June, aboard the hired transport barque Parmelia.

On his way back to England from Ceylon, Fremantle in September 1832 visited the Swan River Colony for a week, but never returned.

In 1833 he stopped at Pitcairn Island, where he tried to resolve a leadership dispute between Joshua Hill and George Hunn Nobbs.
