William Charles Roost (22 March 1924 – 10 February 2013) was a professional footballer who played as an inside forward in The Football League for Bristol Rovers and Swindon Town. Roost's footballing career had a late start, due to the Second World War, eventually making his League debut in 1948 at the age of 24. He previously played for Stonehouse in Gloucestershire where he was spotted by a Bristol Rovers scout, and he joined Rovers initially as an amateur on 10 September. He was awarded his first professional contract after less than two weeks in Bristol, signing on 23 September.
