Chertsey Abbey, dedicated to St Peter, was a Benedictine monastery located at Chertsey in the English county of Surrey. It was founded by Saint Erkenwald, later Bishop of London, in 666. He became the first abbot. In the 9th century it was sacked by the Danes and refounded from Abingdon Abbey by King Edgar of England in 964. Most of north-west Surrey was granted to the abbey by King Frithuwald of Surrey. In late medieval times, it became famous as the burial place of King Henry VI (whose body was later transferred to St George's Chapel, Windsor). The abbey was dissolved by the commissioners of King Henry VIII in 1537 but the community moved to Bisham. The site was given to Sir William Fitzwilliam and now only slight traces remain amongst later buildings. Some very fine medieval tiles from the abbey, some depicting the legend of Tristan and Iseult, may be seen in the British Museum.
