Furzton Lake is a recreational lake in the Furzton area of Milton Keynes, bordered by V4 Watling Street, Shirwell Crescent, Bilbrook Lane, and Lynmouth Crescent.

Originally constructed as a flood-water basin, it has matured into a popular green space for walkers, joggers, and cyclists. National Cycle Route 51 passes through the area. Pedestrian access around the lake is good, with surfaced paths throughout.

A boardwalk on the smaller, more sheltered south-eastern section provides a useful spot for wildlife observation. Multiple car parks serve the lake, and accessible parking is available at Shirwell Crescent and other nearby locations.

Larger accessible vehicles are directed to the Lynmouth Crescent car park.
