HMS ''Roxburgh'' was one of six armoured cruisers built for the Royal Navy in the first decade of the 20th century. She was assigned to the 1st Cruiser Squadron of the Channel Fleet upon completion and was transferred to the reserve Third Fleet in 1909. She was then assigned to the 5th Cruiser Squadron of the reserve Second Fleet in 1912 and the 3rd Cruiser Squadron the following year. Upon mobilisation in mid-1914 her squadron was assigned to the Grand Fleet and spent much of its time patrolling the northern exits from the North Sea and the Norwegian coast. She was torpedoed in mid-1915 by a German submarine and repairs took almost a year. ''Roxburgh'' was transferred to the North America and West Indies Station in mid-1916 and spent the rest of the war escorting convoys. She rammed a German submarine while escorting a convoy in early 1918. She was reduced to reserve in 1919, but recommissioned later that year for use as a radio training ship. The ship was paid off in 1920 and sold for scrap the following year. ==Design and description== ''Roxburgh'' was designed to displace .
