Coe Fen is a semi-rural meadowland area to the east of the River Cam in the south of the city of Cambridge, England. It lies at the back of Peterhouse to the north, the Fitzwilliam Museum, and The Leys School to the south. The fen is straddled by the Fen Causeway across the Cam. There is also a footbridge at the back of The Leys School to the south and Crusoe Bridge is just north of the Fen Causeway Bridge.
