Blisworth Tunnel is a canal tunnel on the Grand Union Canal in Northamptonshire, England between the villages of Stoke Bruerne at the southern end and Blisworth at the northern end. There was some major rebuilding of the tunnel in the 1980s, with sections lined with pre-cast concrete rings. It was also used to test out the materials that were later used on the Channel Tunnel. One of the unused rings is on display just outside the south portal.
