Hartford Marina is a full-service marina situated on the River Great Ouse near Wyton, Huntingdon, in Cambridgeshire, England.

Located between Godmanchester and Houghton Locks, it provides direct access to approximately 140 miles of navigable waterway across the Great Ouse and its tributaries — the Cam, Lark, Little Ouse, and Wissey.

The marina offers more than 200 fixed and floating moorings suitable for river and canal boats of all sizes, set within the Huntingdonshire countryside roughly two miles from the centre of Huntingdon.

Its location off the Huntingdon bypass gives good road connections to London, Cambridge, and Peterborough, making it a practical base for both local boaters and those travelling further afield.
