HMS Skirmisher was a Sentinel-class scout cruiser of the Royal Navy. She was designed to lead destroyer flotillas, but, like the Japanese Tenryū-class, was soon rendered too slow for the role, as destroyers became faster. Nevertheless, Skirmisher served with destroyer flotillas on patrol duty in home waters until 1916, when she was sent to the Mediterranean. She was reassigned to the Aegean in 1917, and remained with that Squadron until the end of the War. Skirmisher's best chance for action came in January, 1918, when the Ottomans sortied from the Dardanelles, but after striking mines, they retired before Skirmisher and her companions could engage. Returning home in 1919, she was placed in reserve, and sold for scrapping in March, 1920.
