Flitwick (/ˈflɪtɪk/ ) is a town and civil parish in Central Bedfordshire, England. It is mentioned in the Domesday Book of 1086 as "a hamlet on the River Flitt". The spelling Flytwyk appears in 1381.

The nearby River Flit runs through Flitwick Moor, a nature reserve and a Site of Special Scientific Interest.

It is broadly equidistant between Bedford 10 mi (16 km) and Luton 10 mi (16 km). It shares many services with the neighbouring town of Ampthill, which lies just to the north. The boundary between the two towns is a watercourse called the Running Waters, which is now the route of the A507.

There are two tiers of local government covering Flitwick, at parish (town) and unitary authority level: Flitwick Town Council and Central Bedfordshire Council. The town council is based at the Rufus Centre on Steppingley Road, which was built in 1999.

Flitwick has seen a large expansion in its population in recent years, but its retail facilities have not kept up with this growth. The local council has drawn up plans to redevelop the town centre to improve its retail offering [1]. At present, it has a Tesco, a Co-op, which provides a secondary food source to the community and many smaller shops and estate agents, many in close proximity to the railway station. There is an open-air market every Friday selling local produce, which is set up on the car park of the village hall. The open-air market has a variety of stalls such as fishmongers, baker, haberdashery, and fruit and vegetables.

The town also opened an Aldi in September 2023.
