Waterston is a village near Milford Haven in Pembrokeshire, Wales, in the community and parish[1] of Llanstadwell.

[4] To the northeast of the village is Scoveston Fort, a Grade II listed structure constructed in the 1860s as part of the defences of Pembroke dockyard.

[5][6] Part of the village now lies within the boundaries of the Dragon LNG terminal.

Costing about £35 million and extending to 300 acres (120 ha), the plant was built as an oil refinery in 1997.
