HMS Bacchante was a Cressy-class armoured cruiser built for the Royal Navy around 1900. Upon completion she was assigned to the Mediterranean Fleet as flagship of the fleet's cruiser squadron. She was reduced to reserve upon her return home in 1905 before returning to the Mediterranean in 1906. Six years later she returned home and was again placed in reserve. Recommissioned at the start of World War I, Bacchante became flagship of the 7th Cruiser Squadron. She was present at the Battle of Heligoland Bight a few weeks after the war began, but saw no combat.

The Cressy-class cruiser was a class of six armoured cruisers built for the Royal Navy around 1900. Their design's incorporation of a pair of 9.2-inch guns and armoured sides served to address criticism directed against the previous Diadem class — advances made possible by their 1,000 ton increase in displacement over their predecessors. The ships were notably stable, except for a susceptibility to pitching.
