Admiral Sir Charles Howe Fremantle GCB RN (1 June 1800 – 25 May 1869) was a renowned British Royal Navy officer. The city of Fremantle, Western Australia, is named after him.
Fremantle joined the Royal Navy in 1812 and worked his way up the ranks on a number of vessels. From 1818 to 1819 he served on his father's flagship in the Mediterranean Fleet.
In 1824 Fremantle received the first gold gallantry medal of the new Royal National Institution for the Preservation of Life from Shipwreck, later the Royal National Lifeboat Institution, for an attempted rescue at Whitepit near Christchurch, Dorset.
In April 1826 Fremantle was charged with raping a 15-year-old girl. His family is said to have paid off witnesses and leant on the judiciary to avoid scandal.
