Gamlingay Cinques Common, sometimes just called Gamlingay Cinques, is a registered village green (39) and a small acid grassland nature reserve and County Wildlife Site located just north-west of the village of Gamlingay, Cambridgeshire, United Kingdom. Managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire, the 3.4 hectares (8.4 acres) site is one of the surviving remnants of the once expansive Gamlingay Great Heath (another being the close by Gamlingay Meadows), a heathland once visited by famous British naturalist Charles Darwin as a university student. The site is open to the public, has both car parking and disabled access facilities, and is a popular site for local walkers, as its dry sandy soil provides a habitat for numerous species of flowering plants.
