Calcutt Marina sits on the Grand Union Canal (Warwick and Napton Canal) in Warwickshire, close to Napton Junction where the Grand Union meets the Oxford Canal. It is operated by Calcutt Boats and set within over 40 acres of grounds.

The marina is located at Calcutt Locks, the three-lock flight that begins the canal's descent toward the Warwickshire River Avon.

Boatyard facilities here include a slipway and dry dock capable of handling craft up to 72 feet in length and 7 feet 6 inches in beam. Leisure moorings, boat hire, and brokerage services are also available on site.
