Guichen was a large protected cruiser built in the 1890s for the French Navy, the only member of her class. She was intended to serve as a long-range commerce raider, designed according to the theories of the Jeune École, which favored a strategy of attacking Britain's extensive merchant shipping network instead of engaging in an expensive naval arms race with the Royal Navy. As such, Guichen was built with a relatively light armament of just eight medium-caliber guns, but was given a long cruising range and the appearance of a large passenger liner, which would help her to evade detection while raiding merchant shipping.
