HMS Powerful was the lead ship of her class of two protected cruisers built for the Royal Navy (RN) in the 1890s. She was initially assigned to the China Station and then provided landing parties which fought in the Siege of Ladysmith of 1899–1900 during the Second Boer War. After a lengthy refit, the ship was placed in reserve until 1905 when Powerful became the flagship of the Australia Station. Upon her return home in 1912, she was again reduced to reserve for a brief time before she was reclassified as a training ship. The ship remained in this role until 1929 when she was sold for scrap.
