Sonning Bridge is a road bridge across the River Thames at Sonning, Berkshire. It links Sonning with Sonning Eye (Oxfordshire) and crosses the Thames on the reach above Shiplake Lock, just short of Sonning Lock. It is a brick arch bridge completed in 1775, to replace an earlier wooden bridge. The bridge has been the subject of many paintings and prints by artists and is a Grade II listed building.

The road extends to the two Sonning Backwater Bridges. One is over the backwater downstream of the weir and the other is over the millrace which is between the two main branches.

The Thames Path crosses the river at this point.

The earliest definite reference to a "timber" bridge is around 1530, although there are claims that there was a wooden old Saxon bridge here before 1125. It was spoken of as being rebuilt in 1604, although throughout the 17th century there are reports of decay and the need for repair.

A stone marker at the centre of the bridge is marked "B | O" (for the counties of Berkshire and Oxfordshire on each side of the river) with the vertical line indicating the exact boundary down the middle of the river. This is an ancient border which used to be between Wessex and Mercia.

The wooden backwater bridges were not replaced until the 20th century. At the beginning of the 20th century, there were complaints about the traction engines causing structural problems with the old wooden backwater bridges and disturbing the peace. In 2013 the frontage of a letterbox was placed on the downstream side of one of the supporting buttresses of the bridge by the artist Impro. The position of the box meant that if it had been functional it would only have been accessible to users on the river itself.

It is rumoured that Dick Turpin used the bridge as an escape route from Berkshire to Oxfordshire to evade the authorities.
