Waterston is a village near Milford Haven in Pembrokeshire, Wales, in the community and parish^[1] of Llanstadwell. It lies on the B4325 road linking Neyland and Milford Haven.^[2]

The built-up area had a population of 335 in 2011.^[3]

Waterston Wesleyan Methodist chapel was built in 1836. It was rebuilt in the 1880s in Gothic style.^[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. It cost £45,462, and was the only one of its kind built.^[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. In 2007 it was redeveloped as a LNG storage facility, and taken over by Dragon in 2009.^[7] The plant is expected to process between 10 and 20 percent of the UK's gas supply requirement.^{[citation needed]}

A large fire in April 2024 at a car breakers in the village took 7 fire crews to extinguish; nearby residents were evacuated for safety. The cause was found to be accidental,^[8] and had been monitored by the close-by Dragon Terminal.^[9] There had been a serious fire in January 2024 in the same industrial estate.^[10]
