Wraysbury is a village and civil parish in the Royal Borough of Windsor and Maidenhead in England. It is under the western approach path of London Heathrow airport. It is located on the east bank of the River Thames, roughly midway between Windsor and Staines-upon-Thames, and 18 miles (29 km) west by south-west of London.

Historically part of Buckinghamshire, Wraysbury was made part of the new non-metropolitan Berkshire in 1974, under the Local Government Act 1972. The Wraysbury Reservoir is located to the east, split in two by the historic border of Buckinghamshire with Middlesex if administratively wholly in the Spelthorne district of Surrey.

Magna Carta Island, in the parish of Wraysbury, is one of the sites traditionally suggested for the sealing of the Magna Carta in 1215.

On the Ankerwycke estate in the village are the ruins of a Benedictine nunnery, founded in the reign of King Henry II. One of the 50 oldest trees in the United Kingdom can be found here: at around 2000 years old, the Ankerwycke Yew dates from the Iron Age, and is so wide that you can fit a Mini Cooper behind its trunk and not see it from the other side. Local legend says that Anne Boleyn once sat under the tree, while residing at the Ankerwycke estate, but this has not been verified.

Henry Stafford, 5th Baron Stafford died at Ankerwycke in 1637. The Ankerwycke estate was bought by John Blagrove, a prominent Jamaican slave owner, who did much to improve the estate.
