Chettisham Meadow is a 0.7 hectare biological Site of Special Scientific Interest west of Chettisham, 3 km north of Ely in Cambridgeshire. It is managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. The site is grassland on calcareous clay, and evidence survives of ridge and furrow medieval farming. Flowering plants include adder's tongue, cowslip and the uncommon green-winged orchid. There is access from Church Farm on the road called The Hamlet, by a track which crosses the A10, and curves to meet the track called The Balk. A footpath from the point where the two tracks meet leads to the reserve entrance.
