HMS Hermione was an Astraea-class Royal Navy protected cruiser launched at Devonport in 1893. She served in World War I and was sold in 1921. She was renamed training ship Warspite in 1922, and broken up in 1940.

The Astraea class was an eight ship class of protected cruisers built for the Royal Navy during the 1890s. The ships served on a number of foreign stations during their careers, particularly in the waters of the Indian and Pacific Oceans, and around the Cape of Good Hope. Already obsolete by the outbreak of the First World War, most continued to see service in a variety of roles, though rarely in a front line capacity. By the end of the war the majority were being used as training or depot ships, and they were soon sold out of the service and scrapped. However, one ship, HMS Hermione, was bought by the Marine Society and used as a training ship until 1940.
