Potton is a town and civil parish in the Central Bedfordshire district of Bedfordshire, England, about 10 miles (16 km) east of the county town Bedford. Its population in 2011 was 4,870. In 1783 the Great Fire of Potton destroyed a large part of the town. The fire started in a stack of clover in a field in the area of what is now Spencer Close, in 1783. King Street, half the Market Square and some of the Brook End area were destroyed. It was reported to have burned for a day. Local people raised £6,000 to help those most in need. The 13th-century parish church, St Mary's, survived. Rebuilding after the fire has left the town with a number of Georgian buildings. The parish church dates from the 13th century, and is dedicated to St Mary.

Potton's horse fairs were some of the largest in the country.

Potton Manor was built in the 1860s. It was requisitioned by the armed forces and used as a laboratory during the war and as a car factory by Eva Pokorova and Otto van Smekal. The Champion car built in Potton was purchased from the National Motor Museum by Potton History Society, whose aim it is to restore the vehicle to full working order. The house was finally demolished in the early 1980s.
