The third HMS ''Illustrious'' of the British Royal Navy was a pre-dreadnought battleship. The ship was built at the Chatham Dockyard; her keel was laid down in March 1895, her completed hull was launched in September 1896, and she was commissioned into the fleet in April 1898. She was armed with a main battery of four guns and a secondary battery of twelve guns. The ship had a top speed of . ''Illustrious'' was assigned to the Mediterranean Fleet until 1904. Transferred to the Channel Fleet (which was subsequently reorganised to the Atlantic Fleet) she underwent a refit which was duly completed in early 1906.

One of the oldest battleships in the Royal Navy when World War I broke out, she served as a guard ship at various regions around Northern England until late 1915.

She had a crew of 672 officers and enlisted men. The ship was armed with four BL 12-inch Mk VIII guns in twin turrets, one forward and one aft. The turrets were placed on circular barbettes, unlike six of her sisters, which retained earlier pear-shaped barbettes. ''Illustrious'' also carried twelve QF 6-inch /40 guns. They were mounted in casemates in two gun decks amidships. She also carried sixteen QF 12-pounder guns and twelve QF 2-pounder guns. She was also equipped with five torpedo tubes, four of which were submerged in the ship's hull, with the last in a deck-mounted launcher. ''Illustrious'' and the other ships of her class had 9 inches (229 mm) of Harvey armour, which allowed equal protection with less cost in weight compared to previous types of armour.
