Hannington is a village and civil parish in Wiltshire, England, about 2 miles (3.2 km) north-west of Highworth, within the Borough of Swindon. The parish includes the hamlets of Hannington Wick (north of Hannington village) and Swanborough (south, on the border with Highworth parish). The River Thames forms both the northern boundary of the parish and the county boundary with Gloucestershire.

John Marius Wilson of the Imperial Gazetteer of England and Wales in 1870 described the village of Hannington as:

A village and a parish in Highworth district, Wilts. The village stands 2 miles W by N of Highworth, 2 S of the river Thames at the boundary with Gloucester, and 7 NE of Swindon Junction r. station; is a pretty place, built in the form of the letter Y; and has a post office under Swindon.

The parish of Hannington had a population of 240 at the 2011 census. 433 people lived in Hannington in 1841. Numbers then steadily declined, and since the 1940s the parish population has plateaued around the 250 mark.

The occupations recorded for the parish in 1881 are shown in the graph (left). They were dominated by agriculture with 46 people, almost all male, while those employed in domestic service were almost all female.

Hannington Hall is a Grade II* listed country house built in 1653, which has been a centrepiece of the village since Sir Thomas Freke commissioned and paid for its construction. The grounds of the hall are dotted with buildings associated with the running of the estate such as the Victorian stable block.

The Grade II* listed Church of England parish church is dedicated to John the Baptist. It was rebuilt in 1869–1871, retaining two 12th-century doorways and the 15th-century tower.

Today, the church is within the benefice of Highworth with Sevenhampton and Inglesham and Hannington, centred on St Michael's church at Highworth.
