Blue Water Marina is a boatyard facility situated on the Stainforth and Keadby Canal, part of the Sheffield and South Yorkshire Navigation.

It lies between Stainforth Junction to the west and Keadby Visitor Moorings to the east, with Hatfield Road Railway Bridge and Wykewell Lift Bridge as its nearest neighbours along the waterway. The marina offers boaters gas for sale and a pump-out service.

Visitor mooring at the site is not available. It is noted on open canal mapping as also providing water, toilets, showers, an Elsan point, and diesel, making it a useful service stop for boats travelling this stretch of the navigation.
