Furzton Lake is a 70-acre balancing lake in the Furzton area of Milton Keynes, bordered by V4 Watling Street, Shirwell Crescent, Bilbrook Lane, and Lynmouth Crescent.

Originally constructed to act as a flood basin, it has matured into a popular green space attracting joggers, cyclists, walkers, and wildlife enthusiasts. National Cycle Route 51 passes through the area.

Pedestrian access around the lake is good, with surfaced paths suitable for wheelchairs and mobility aids. Three free car parks serve the site.

A boardwalk on the smaller, more sheltered south-east section of the lake provides a good spot for wildlife observation. The lake is also well known for fishing, with carp, bream, roach, and perch among the species present.
