Eight ships of the Royal Navy have been named HMS Beagle, after the beagle (a type of dog). All are obscure except for the second Beagle, 1820–1870, that transported Charles Darwin around the world.
The first Beagle was a Cruizer-class brig-sloop in service from 1804 to 1814.
The second Beagle was a 10-gun Cherokee class brig-sloop , launched in 1820, converted to a survey ship in 1825, a customs watchvessel in 1846, and sold in 1870.
The third Beagle was a wooden-hulled screw gunboat launched in 1854 and sold in 1863, eventually becoming the Japanese vessel Kanko.
