The Riddy is a flood meadow and Local Nature Reserve located in Sandy, Bedfordshire, United Kingdom, bordering the River Ivel. Owned by Sandy Town Council but managed by both the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire and Bedfordshire Rural Communities Charity, the 7.7 hectares (19 acres) site gains its name from a small stream which flows through the eastern end of the reserve. The different habitats in the Riddy support a diverse range of species, including a multiplicity of grasses and flowering plants in the meadows, aquatic plants and water voles which inhabit the ditches, ponds and stream, and birds which feed and hunt across the reserve.
