Copmanthorpe (ˈkɒpmənˌθɔːrp) is a village and civil parish in the City of York in the English county of North Yorkshire, south-west of York, west of Bishopthorpe and close to Acaster Malbis, Askham Bryan and Askham Richard. According to the 2001 census the parish had a population of 4,262, reducing to 4,173 at the 2011 Census.
The village was historically part of the West Riding of Yorkshire until 1974. It was then a part of the district of Selby District in North Yorkshire from 1974 until 1996. Since 1996 it has been part of the City of York unitary authority. The village is part of the York Outer constituency.
The village is mentioned in the Domesday Book as Copemantorp, from Old Norse Kaupmanna þorp, meaning Traders' Village or Craftsmen's Village. The area of Copmanthorpe covering Main Street, Church Street and Low Green became a Conservation Area in 1978.
Copmanthorpe is bounded to the north by the A64, while the East Coast Main Line runs through its south-east periphery; to the west lies open countryside.
The Roman road from York (Eboracum) to Tadcaster (Calcaria) runs to the north of the village centre, along what are now Top Lane, Hallcroft Lane and Colton Lane.
It is recorded that the Lord of Copmanthorpe Manor was an Anglo-Saxon, named Gospatrick, at the time of the Norman invasion of England. According to the Domesday Book, the title was handed to Erneis de Burun in 1084, when he became Sheriff of Yorkshire.
Members of the Vavasour family were resident in the village from the 17th until the 20th century. A William Vavasour of Copmanthorpe is recorded in the Battle Abbey Roll. The Vavasour family were the holders of the Barotnetcy of Haselwood near Tadcaster from 1628, which included estates in Killingthorpe, Spalington and Copmanthorpe. Sir William Vavasour was the first and only Baronet of Copmanthorpe in 1643 until his death in 1659 and was the son of the Knight Marshall, Sir Thomas Vavasour. In 1672 the manor was sold to the Wood family.
