Carlbury is a hamlet in the civil parish of High Coniscliffe in County Durham, in England.

After Sir Thomas was executed for treason in 1322, Carlbury went back to the widow's family and thence to the House of Neville.

[6] During the Civil War on 1 December 1642 a contingent of Royalists, led by the Earl of Newcastle and travelling south along Dere Street, met a group of Parliamentarians, led by Captain Hotham and travelling north, in a dispute over the bridge at Piercebridge.

[5] In 1875 on that same Carlbury Hill, architect John Ross built Carlbury Hall in Scots baronial style for National Provincial Bank manager Thomas McLachlan; McLachlan is said to have chosen the site where the view of the River Tees would remind him of Scotland.

[6] By 1905 Carlbury Hall was in the hands of James Backhouse Dale (born 1855), a company director of Hordern Collieries Ltd,[8][9] and between 1909 and 1929 it was owned by John Henry Pease, a member of Cleveland Naturalists' Field Club.

[14][15] Mortaria dated around 170–180 AD with painted inscriptions have been found in Carlbury Vale west, and they could be associated with Piercebridge Roman Fort.

[16] In 2005–2006, Carlbury still had 3.5 hectares of ancient woodland, classified as a Site of Nature Conservation Importance and a wildlife corridor.
