Walton-on-Thames /ˈwɔːltən ɒn ˈtɛmz/ is a town in the Elmbridge borough of Surrey in South East England. The town is located 15.3 miles (24.6 km) south west of Charing Cross and is between the towns of Weybridge and Molesey. It is situated on the River Thames between Sunbury Lock and Shepperton Lock.
The name "Walton" is Anglo-Saxon in origin and is believed to mean "farm of the Britons" or "Saxon settlement". Even before the Romans and the Saxons were present, there was a Celtic settlement here. The Anglo-Saxon word for the Celtic inhabitants who lived here before them is "Wealas". Walton was also identified by William Camden as the place where Julius Caesar forded the River Thames on his second invasion of Britain. However, according to the Elmbridge Museum, there is no evidence to support this.
Walton lay within the Anglo-Saxon administrative district of the Elmbridge hundred.
