Denny Abbey is a former abbey near Waterbeach, about 6 miles (10 km) north of Cambridge in Cambridgeshire, England. It is now the Farmland Museum and Denny Abbey. The monastery was inhabited by a succession of three different religious orders. The site is a scheduled ancient monument. The church and refectory buildings survive and are Grade I listed buildings. Also on the site is a barn built in the 17th century from stone taken from the abbey. The place-name "Denny" is first attested in Templar records of 1176, where it appears as Daneya and Deneia. The name is thought to mean "Danes' Island".
