Rothbury is a town and civil parish in Northumberland, England. It is located on the River Coquet, northwest of Morpeth and north-northwest of Newcastle upon Tyne. At the time of the United Kingdom Census 2001, Rothbury had a population of 1,740.
Rothbury emerged as a relatively important town in the historic district of Coquetdale because of its situation at a crossroads over a ford along the River Coquet. Turnpike roads leading to Newcastle upon Tyne, Alnwick, Hexham and Morpeth allowed for an influx of families and the enlargement of the settlement during the Middle Ages. Rothbury was chartered as a market town in 1291, and became a centre for dealing in cattle and wool for the surrounding villages well into the Early Modern Period.
Today, the town is used as a staging point for recreational walking. Landmarks in and around Rothbury include the Victorian era mansion Cragside, the Simonside Hills and Northumberland National Park. In July 2010, Rothbury was the centre of a high-profile police manhunt.
