Braunston Marina sits on the Grand Union Canal at Braunston, Northamptonshire, near the historic junction where the Grand Union meets the Oxford Canal.

The marina occupies the site of the former Nurser's boatyard, and its dry dock was built on the line of the original Oxford Canal junction, bypassed when the Oxford Canal was straightened in 1805.

It is widely regarded as one of the most historically significant boatyards on the English canal network.

The marina serves both permanent moorers and visiting boats, offering a full range of boatyard services including a dry dock, slipway, wet dock, diesel, chandlery, boat sales, and maintenance and repair facilities.

It is also known as the home of an annual Historic Narrowboat Rally, drawing enthusiasts from across the country.
