HMS Apollo, the sixth ship of the Royal Navy to be named for the Greek god Apollo, was a second-class Apollo-class protected cruiser launched in 1891 and converted to a minelayer in 1909 along with six of her sisters. They formed a minelaying squadron in 1914–15 during the First World War, although Apollo was disarmed in 1915 and served in secondary roles until sold for breaking up in 1920.
