Willington is a town and former civil parish, now in the parish of Greater Willington, in County Durham and the ceremonial county of Durham, England. Willington stands in the foothills of the Pennines and near the River Wear close to Crook, Bishop Auckland and Durham.

Like many communities in the area Willington's economy was largely based on coal mining. The closure of the colliery in 1967 therefore affected the local economy.

The name Willington derives from the Old English wifelingtūn meaning the 'settlement connected with Wifel'.

Willington is in the electoral ward of Willington and Hunwick. The population of this ward at the 2011 Census was 9,147.

Willington was formerly a township and chapelry in the parish of Brancepeth, from 1866 Willington was a civil parish in its own right, on 1 April 1937 the parish was abolished to form Crook and Willington, part also went to Bishop Auckland. In 1931 that parish had a population of 6644.

There are large areas of parkland with play areas in the town.

A leisure centre existed in the village, Spectrum Leisure Centre (a registered charity), but this closed following bankruptcy proceedings in 2024. The centre had a large sports hall, gyms and a bar/refreshment area and hosted events, notably those of Empire Electric Palace Theatre (Crook).

Willington has multiple primary schools and a secondary school.
