HMS Vengeance was a pre-dreadnought battleship of the British Royal Navy and a member of the Canopus class. Intended for service in Asia, Vengeance and her sister ships were smaller and faster than the preceding Majestic-class battleships, but retained the same battery of four 12-inch (305 mm) guns. She also carried thinner armour, but incorporated new Krupp steel, which was more effective than the Harvey armour used in the Majestics. Vengeance was laid down in August 1898, launched in July 1899, and commissioned into the fleet in April 1902.
