Newton St Loe is a small Somerset village and civil parish located close to the villages of Corston and Stanton Prior, between Bath and Bristol in England. The majority of the village is owned by the Duchy of Cornwall. The parish has a population of 681.

The Duchy of Cornwall is one of two royal duchies in England, the other being the Duchy of Lancaster. The eldest son of the reigning British monarch obtains possession of the duchy and the title of Duke of Cornwall at birth or when his parent succeeds to the throne, but may not sell assets for personal benefit and has limited rights and income while a minor.
