HMS Doterel was a Doterel-class sloop launched by the Royal Navy in 1880. She sank at anchor off Punta Arenas after an explosion on 26 April 1881. Her loss caused the deaths of 143 crew members, and there were 12 survivors. She was en route to join the Pacific Station. Her loss was initially the source of much speculation. Causes considered included an attack by the Fenians, a lost torpedo, and a coal gas explosion. An enquiry in September 1881 concluded coal gas was the cause.
