Ramsden Corner Plantation is a 3.2-hectare (7.9-acre) biological Site of Special Scientific Interest west of Northampton. It is managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire.

A stream runs through this valley site, which is acidic grassland, woodland and scrub on clay and sand. Plants such as wood millet, wood-sorrel and wood vetch are indicators of ancient woodland. Opposite-leaved golden-saxifrage is found in wet flushes.

The Macmillan Way runs along its southern boundary. There is access from Main Street between Farthingstone and Upper Stowe.
