The Long Sunset is a 1955 play by English writer R. C. Sherriff. It is set in AD 410, at the end of the Roman occupation of Britain. The play was inspired by Sherriff's love of history, and in particular by the excavation of the Roman villa at Angmering in West Sussex, which he bankrolled and participated in during the late 1930s and early 1940s. The first two years of the excavations were supervised by Leslie Scott.
