The Port of Mostyn Ltd is a privately owned and operated port located in North Wales in the outer estuary of the River Dee.  It is a Statutory Harbour  Authority and also the Statutory Pilotage Authority for navigation in the estuary.

As one of the oldest ports in the country, Mostyn has a long history of handling cargoes including steel, timber and woodpulp, and also bulk cargos of coal, iron ore, woodchip and sulphur for the region’s heavy industries of the time. 

Animal feedstuffs and fertilizers for the agricultural sector of north Wales and the north-west and midlands of the U.K. were also handled at the Port. 

Over recent years however, Mostyn has become one of the main centres in Europe for the assembly and installation of turbines; a large portion of its business is now dedicated to the offshore renewable energy sector.
