Iver and Iver Heath (occasionally also known as Evreham) are two villages in the very south eastern corner of Buckinghamshire, England. They are located to the east of the town of Slough, next to the M25 motorway.

The village name 'Iver' is Anglo Saxon in origin, and means '(place by) the brow of the hill'. 'Evreham' has a similar etymology, meaning 'homestead by the brow of a hill'. In the Domesday Book of 1086 the whole area was recorded as Evreham, and was in the possession of a man called Robert Doiley.

It has been suggested by some that the area is actually named after a contemporary of Doiley, Roger de Iveri, also a Norman gentleman who arrived in England with William the Conqueror. However there are no records to suggest that Iveri ever owned the manor here, although he did own property elsewhere in Buckinghamshire.

The area was once (in 1351) granted a Royal charter to hold a weekly market. This charter was confirmed 110 years later in 1461. At that time Iver was a place of some importance.

The family names Eure and Ewer are said to originate from this area.
