Port Mahon Dockyard was a Royal Navy Dockyard located at Port Mahon, Menorca, Spain. It was opened in 1708 and in 1802 the port was ceded back to Spain. However a resident commissioner of the Royal Navy was still appointed as late as 1814. The dockyard was administered by the Navy Board and was part of the Mediterranean Fleet.
