Thetford Town F.C. is an English football club based in Thetford, Norfolk. The club are currently members of the Premier Division of the Eastern Counties League and play at Mundford Road. The club is affiliated to the Norfolk County FA.
The club was established in 1883 and moved to its current ground on Mundford Road in 1905. They played in the Norwich and District League until World War I, but due to the town’s position on the Norfolk-Suffolk border, the club could enter cups in both counties, and in 1911 were victorious in the Suffolk Junior Cup final.
After the war they played in leagues in both Norfolk and Suffolk until becoming founder members of the Eastern Counties League in 1935. However, they finished bottom in both 1935–36 and 1936–37 and returned to the county leagues. In 1948 they won the Norfolk Senior Cup, and in 1954–55 were Norfolk & Suffolk League champions.
In 1963 the club rejoined the Eastern Counties League. However, they never finished higher than fifth, and were bottom in both 1983–84 and 1984–85. In 1989–90 the club finished as runners-up in the Premier Division. Although they won the Norfolk Senior Cup final the following season, in 1991–92 they were relegated to Division One after finishing bottom. The club finished bottom of Division One in 1998–99 and 1999–2000, but were not relegated.
In 2011–12 the club finished second in Division One and were promoted to the Premier Division.
