HMS Warrior was a Warrior-class armoured cruiser built for the Royal Navy in the first decade of the 20th century. She was stationed in the Mediterranean when the First World War began and participated in the pursuit of the German battlecruiser SMS Goeben and light cruiser SMS Breslau. Warrior was transferred to the Grand Fleet in December 1914 and remained there for the rest of her career. She was heavily damaged during the Battle of Jutland in 1916, after which she withdrew and was later abandoned and sank in a rising sea.
