Flitwick is a town and civil parish in 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.

There is a sports centre with a 25-metre swimming pool with kids' pool attached. The leisure centre also has a gym, squash courts with leagues, and a gymnasium.
