HMS Terror was an Erebus-class monitor built for the Royal Navy in 1915-1916 at the Harland and Wolff shipyard in Govan, Scotland.

The Erebus-class monitors were of 7,200 long tons (7,300 t) displacement, 405 ft (123 m) long, with a maximum speed of 12 kn (22 km/h; 14 mph) produced by reciprocating engines with two shafts, and a crew of 223. The ship's main armament consisted of two, BL 15 inch Mk I naval guns in a single forward turret. This turret had been built as a spare for Furious.

The original secondary armament of two 6 in (152 mm) mounts was soon replaced by eight 4 in (102 mm) guns in single mounts and two 3 in (76 mm) anti-aircraft guns, also in single mounts. Between the wars, the 4 inch low angle guns were replaced by anti-aircraft mounts and the 3 inch guns by eight 0.50 in (12.7 mm) anti-aircraft Vickers machine guns in two quadruple mounts.

The class mostly served in the Naval Gunfire Support role.

Terror joined the Dover Patrol in August 1916 and operated against German forces on the coast of occupied Belgium. On 19 October 1917, she was torpedoed by German motor torpedo boats off Dunkirk. There were no casualties and the ship was beached before being towed back to Portsmouth. The damage took three months to repair. In April 1918, Terror was in the Long Range Bombardment force for the Zeebrugge raid with her sister ship Erebus and destroyers Termanent, Truculent, and Manley. On 27 September, Terror, along with her sister ship Erebus, provided gunnery support for the Fourth Battle of Ypres. In the early 1920s, she was used for gunnery trials against several old warships including SMS Baden and HMS Superb.
