HMS Childers was a Royal Navy 18-gun Cruizer-class brig-sloop that Nicholas Diddams built at Portsmouth Dockyard and launched in 1812.

[1] When news of the outbreak of the War of 1812 reached Britain, the Royal Navy seized all American vessels then in British ports.

Childers was among the 42 Royal Navy vessels then lying at Spithead or Portsmouth and so entitled to share in the grant for the American ships Belleville, Janus, Aeos, Ganges and Leonidas seized there on 31 July 1812.

[2][a] Commander John Bedford replaced Bluett in August and sailed for the Leeward Islands on 29 September.

During Astley's command, yellow fever attacked the crew of Childers, forcing him to bring her into English Harbour, Antigua, with only 15 men available for duty.
