HMS Victoria was a 121-gun screw first-rate ship of the line built for the Royal Navy during the 1850s. She and her sister ship HMS Howe were the only British three-decker ships of the line to be designed from the start for screw propulsion, and were the largest wooden battleships of their time. She was the world's second-largest wooden battleship after Howe. She was also the world's second largest warship until the completion of HMS Warrior, Britain's first ironclad battleship, in 1861. Although the ship was completed in 1860, she was not commissioned until 1864 when Victoria became the flagship of Britain's Mediterranean Fleet. She was paid off in 1867 into the reserve fleet and was sold for scrap in 1893.
