The Monument to the Mersey Tunnel stands in Chester Street, Birkenhead, Wirral, Merseyside, England, near the western entrance to the Queensway Tunnel, one of the two Mersey Tunnels carrying roads under the River Mersey between Liverpool and the Wirral. It consists of shaft with a light on the top, and originally had the dual purpose of being a monument and of illuminating the entrance to the tunnel. It was designed by Herbert James Rowse, and was one of a pair, but the monument that was on the Liverpool side of the River Mersey no longer exists. The monument is recorded in the National Heritage List for England as a designated Grade II listed building.
