St Fagans (/ˈfæɡənz/ FAG-ənz;[1] Welsh: Sain Ffagan) is a village and community in the west of the city of Cardiff, capital of Wales.

The name of the area invokes Saint Fagan, according to William of Malmesbury a second-century missionary to Wales but for whom there is no reliable historical evidence.

St Fagans lies on the River Ely, and previously had a railway station on the South Wales Main Line, and currently there is a level crossing.

In 2017 construction started on a new Cardiff suburb of 7,000 houses, named Plasdwr, on countryside between St Fagans, Fairwater and Radyr.

All candidates were therefore elected unopposed, with three other seats filled through councillors being co-opted by members of the community council.
