The Oxford Canal is a 78-mile-long (126 km) narrow canal linking Oxford with Coventry via Banbury and Rugby. It connects with the River Thames at Oxford, to the Grand Union Canal at the villages of Braunston and Napton-on-the-Hill, and to the Coventry Canal at Hawkesbury Junction in Bedworth just north of Coventry.

The canal was once an important artery of trade between the English Midlands and London, and is now highly popular among pleasure boaters.
