Thornton Bridge is a civil parish in North Yorkshire, England, situated between Boroughbridge to the south-west, and Thirsk to the north-east.

[4] The Domesday Survey listed Thornton Bridge as being six carucates of land and belonging to Gospatric, however by the 13th century it was in the hands of the Mowbray family.

[7] Previously the river was crossed by a stone bridge of three arches, which Leland described as "the depe and swift stream of Swale.

"[8] The newer iron bridge dates back to 1865 and stretches in a single span of 98 feet (30 m) over the river.

[11] Thornton Bridge Hall was a manor-house in the area being the home of various noble families (Courtenay, Nevil, Tancard and Strickland), which was largely renovated in 1804.
