Wiston Roman fort is an auxiliary fort in Pembrokeshire, southwest Wales, discovered through aerial photography during the dry summer of 2013 and partially investigated by Dyfed Archaeological Trust in 2013–2014. It represents one of the westernmost known Roman military installations in Britain, almost certainly dating to the conquest and consolidation period of the late 1st century AD, likely linked to the Flavian campaigns of Frontinus and Agricola against the Demetae and Silures.

The fort substantially extends the known footprint of Roman military occupation into southwest Wales, an area previously thought largely devoid of Roman presence beyond Carmarthen (Moridunum). It suggests a more systematic network of garrisons controlling the Demetae territory and the routes across Pembrokeshire, possibly connected to coastal supply or to exploiting local resources.
Geophysical survey and limited excavation revealed a playing-card-shaped enclosure with defensive ditches and ramparts of standard auxiliary fort form, with internal features consistent with timber barrack-style buildings; an associated annexe or vicus indications have also been suggested. Datable finds have been sparse, and the fort remains only partially published, so its precise garrison, duration of occupation, and relationship to other Welsh forts are not yet firmly established.
