The Gloucester Valley Battle Monument is a memorial in South Korea that commemorates the actions of the Gloucestershire Regiment during the Battle of the Imjin River in 1951.
Hill 235, where the 1st Battalion, the Gloucestershire Regiment (the Glorious Glosters) was ordered to "Hold on where you are", is remembered as "Gloster Hill". The hill is south of the Imjin River and west of the Seolmacheon stream at Jeokseong-myeon, Paju City, Gyeonggi-do Province, South Korea.
The memorial stands at the foot of Gloster Hill, beside the Seolmacheon stream, and the British Embassy in Seoul organises services for veterans on every anniversary of the battle. Information on and artifacts from the battle are held by The Soldiers of Gloucestershire Museum.
