HMS Foresight was one of two Forward-class scout cruisers built for the Royal Navy during the first decade of the 20th century. The ship was in reserve for most of the first decade of her existence. After the beginning of the First World War in August 1914, she was initially assigned to the Dover Patrol and was then transferred to the 8th Destroyer Flotilla. Foresight was sent to the Mediterranean in mid-1915 and was then assigned to the Aegean Sea a year later, together with her sister ship, Forward, and remained there until the end of the war. After returning home in 1919, she was sold for scrap in 1920.
