Maryport Marina sits at the mouth of the River Ellen where it meets the Solway Firth in Maryport, Cumbria. A 180-berth, 4-Star Gold Anchor facility, it occupies a historic harbour once central to coal and iron export and shipbuilding.

Access to the marina is controlled by a flap gate that operates when water reaches 5. 5 metres over chart datum, opening a window of roughly four to five hours per tide. The marina can be reached by VHF on Channel 12, callsign "Maryport Marina."

Operational staff are available to carry out a range of professional boat services, and the marina serves as a practical base for cruising the Solway Firth coastline.
