The River Avon (/ˈeɪvən/ AY-vən) is a river in the southwest of England. To distinguish it from a number of other rivers of the same name, it is often called the Bristol Avon. The name 'Avon' is loaned from an ancestor of the Welsh word afon, meaning 'river'.
The Avon rises just north of the village of Acton Turville in South Gloucestershire, before flowing through Wiltshire into Somerset. In its lower reaches from Bath (where it meets the Kennet and Avon Canal) to the Severn Estuary at Avonmouth near Bristol, the river is navigable and is known as the Avon Navigation.
