Stowe Hill Marina sits on the Grand Union Canal just south of Weedon, in Northamptonshire, where the canal curves around Stowe Hill while the railway passes through a tunnel beneath it.

The marina operates as a service facility and boat sales yard, with Rugby Boat Sales and a service wharf located on the same stretch. Visitor moorings at Stowe Hill allow stays of up to 14 days, and a water point is situated nearby close to Bridge No. 26.

The Narrow Boat pub is within a short walk, making this a convenient stopping point for boaters travelling between Weedon and Gayton Junction on the main Grand Union line.
