Gowerton (Welsh: Tre-gŵyr ^ⓘ) is a large village and community, about 4 miles (6 km) northwest of Swansea city centre, Wales. Gowerton is often known as the gateway to the Gower Peninsula. Gowerton's original name was Ffosfelin. The village falls within the Gowerton electoral ward of the City and County of Swansea Council, which elects one councillor. The community had a population of 5,212 and the built-up area with Waunarlwydd 8,183.

In 1980, the Welsh National Eisteddfod (named after Dyffryn Lliw, see below) was held at the Elba sports complex in the village. The Eisteddfod stone (Gorsedd stones) is located on the roundabout (grid ref. 585966) on the B4295 road to Penclawdd.

Nearby villages/towns are Penclawdd (west), Three Crosses and Dunvant (south), Waunarlwydd (east, contiguous with Gowerton), Gorseinon (north) and Loughor (north-west).

From 1974 to 1966, Gowerton was part of the district of Lliw Valley (Dyffryn Lliw) within West Glamorgan.

People from Gowerton are often referred to as "starch". When the local area processed steel for export, the steel owners and white-collar workers lived in the Gowerton area; hence the name "starch". On the other hand, many of the manual workers resided in neighbouring Penclawdd and are known by the affectionate term "donks".^{[citation needed]}

Gowerton is twinned with La Gacilly in Brittany, France.

Gowerton elects a community council of thirteen members in two wards: East and West.

Gowerton has three schools: Gowerton Primary school, Gowerton Comprehensive School and Ysgol Gyfun Gŵyr (Welsh medium comprehensive school).
