Welshpool (Welsh: Y Trallwng) is a town in Powys, Wales, only 4 miles (6 km) from the border with England.

The town is low-lying on the River Severn; the Welsh language name Y Trallwng literally meaning 'the marshy or sinking land'.

In English it was initially known as Pool but its name was changed to Welshpool in 1835 to distinguish it from Poole in Dorset.

Welshpool contains much Georgian architecture and is just north of Powis Castle.

Welshpool served briefly as the capital of Powys Wenwynwyn or South Powys after its Prince was forced to flee the traditional Welsh Royal site at Mathrafal in 1212. After 1284 Powys Wenwynwyn ceased to exist. 'The long mountain' plays as a backdrop to most of Welshpool, which once served as the ultimate grounds for defence for fortresses in the times when the town was just a swampy marsh.

The town was devastated by the forces of Owain Glyndwr in 1400 at the start of his rebellion against the English King Henry IV. Today the waymarked long-distance footpath and National Trail Glyndwr's Way runs through the town.

In 1411 the priest at the church of St. Mary's & St. Cynfelin's was Adam of Usk.

St Cynfelin is reputed to be the founder of the Church in "the age of the saints in Wales" in the 5th century and 6th century AD.
