Pembroke Dockyard is a former Royal Navy dockyard in Pembroke Dock, Pembrokeshire, Wales. It was founded in 1814, although not formally authorized until the Prince Regent signed the necessary Order in Council on 31 October 1815, and was known as Pater Yard until 1817. The Mayor of Pembroke had requested the change 'in deference to the town of Pembroke some two miles (3.2 km) distant'.
