Abergwili (Welsh pronunciationⓘ) is a village and community in Carmarthenshire, Wales, near the confluence of the rivers Towy and Gwili, close to the town of Carmarthen.

Named after the village of Abergwili, the community includes the settlements of Peniel, Llanfihangel-uwch-Gwili and White Mill.

The grounds of the former Bishop's Palace are listed on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

The building is believed to have been built between 1283 and 1291, when Thomas Bek was made bishop of St Davids.

In 1974 the old episcopal palace was purchased by Carmarthenshire County Council for use as a museum, whilst a new residence for the bishops, "Llys Esgob", was built in part of the grounds, together with Diocesan Offices - thereby continuing a connection with Abergwili which has now lasted for well over 400 years.

[2] Until 1802 the river Towy ran past the back of the Palace; it changed course and left an oxbow lake.

[4] Abergwili has seen a substantial increase in population in recent years with new property developments but has kept its character and rural tranquility.
