The River Dorn is a river in Oxfordshire, England, that is a tributary of the River Glyme. The river rises from the limestone uplands of north Oxfordshire, about east of Chipping Norton, and flows southeast past Little Tew; through Sandford St. Martin, where it forms part of Sandford Park's gardens; and through the Bartons: Westcott Barton, Middle Barton, where Cockley Brook joins it, and Steeple Barton — before it joins the River Glyme just east of Wootton .
The River Dorn flows though the Soho Farmhouse members club, part of Soho House (club)[1] between Little Tew and Stanford St Martin.
