Sonning is a village and civil parish in Berkshire, England, on the River Thames, east of Reading. The village was described by Jerome K. Jerome in his book Three Men in a Boat as "the most fairy-like little nook on the whole river".

The parish of Sonning originally included Charvil, Woodley and Earley and, before the formation of civil parishes in 1866, was a cross-county-boundary parish containing Sonning Eye, Dunsden Green and Playhatch in Oxfordshire as well. It is now much smaller and triangular shaped. The ecclesiastical parish of Sonning continues to include Sonning, Charvil and Sonning Eye.

The northwestern boundary is formed by the River Thames before passing through the middle of the Thames Valley Park. The southern border follows the railway line. The northeastern boundary travels over Charvil Hill and follows the edge of the housing at Charvil itself until it reaches the confluence of St Patrick's Stream with the Thames, near St Patrick's Bridge. The northern corner of the parish consists of very low-lying land adjoining the River. The Sonning Golf Course sits in the southeast corner, with Holme Park, Sonning Hill and the business park in the southwest, and the village roughly in the middle.

Sonning village is at a crossing point of the River Thames, where the narrow arched Sonning Bridge on the B478 crosses the river to the hamlet of Sonning Eye on the Oxfordshire bank. Just upstream of the bridge is Sonning Lock. The old village is now joined to further housing along Pound Lane and the A4 Bath Road. It lies some four miles east of the major town of Reading. In other directions, this would put it within the Reading suburban sprawl, but Sonning remains a clearly delineated small village. Most of the village together with the grounds of Reading Blue Coat School forms a Conservation Area.

The historical name of the village is Sunning, derived from the name of the Old English Sunna.

Sonning is home to George Clooney, American film star, and his British wife, the human rights lawyer Amal.
