The Old Town Hall is a former municipal building in the High Street, Biggleswade, Bedfordshire, England.

The new building was designed by James Tacy Wing of Bedford in the neoclassical style, built by William Twelvetrees of Biggleswade in brick with a stucco finish at a cost of £800 and was completed in 1844.

A projecting clock, made by Richard Cawse of Biggleswade, was installed on the north wall in 1898.

[7] The council moved its meetings to the Masonic Rooms (also known as St Andrew's Rooms) on St Andrew's Street in October 1926,[8][9] and the local magistrates' court hearings, which had also been held in town hall, moved to a new courthouse in Saffron Road in October 1927.

[13] A programme of works, to convert the building into a performing arts venue known as The Bigg Theatre, was initiated in June 2023.
