Kempston is a town and civil parish located in Bedfordshire, England. Once known as the largest village in England,^{[citation needed]} Kempston is now a town with its own town council. It has a population of about 20,000, and together with Bedford, it forms an urban area with around 100,000 inhabitants, which is the sole significant urban area in the Borough of Bedford. Kempston serves principally as a dormitory town for Bedford and for Milton Keynes, which is about ten miles away.

Until the 19th century Kempston was a mainly rural parish. It was one of the largest in Bedfordshire with an area of 5,025 acres (20 km²) at the time of enclosure in 1804, and was in Redbournestoke Hundred. Historically there was no central village, but instead settlement was divided between a number of hamlets called "Ends", for example, Up End, Wood End and Box End. Kempston's parish church, All Saints, was in Church End, which was not the largest end but is fairly central. In the 19th century East End, Bell End and Up End began to coalesce into a larger settlement. In 1870 developers began to attempt to develop land on the road from Kempston to Bedford under the name "Kempston New Town". Construction was slow at first, but the new district soon began to expand steadily and Kempston acquired a more urban feel. In 1896 the parish was divided into Kempston Urban District 1,255 acres (5.1 km²) and the civil parish of Kempston Rural 3,770 acres (15 km²).
