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 (one of the University of Cambridge colleges) to the north, the Fitzwilliam Museum, and The Leys School to the south. The fen is straddled by the Fen Causeway (A1134 road) across the Cam.
