The River Tyne Police was a police force which patrolled the River Tyne in England. It was formed in 1845 and later became a police force under the Police Act 1919; its members had full police powers. From 30 November 1949 it also took over responsibility for policing on the property of the Tyne Improvement Commission from the disbanded Tyne Improvement Commission Docks and Piers Police.
On 1 August 1968, the force became part of South Shields Borough Police, which merged with Durham County Constabulary on 1 October 1968. In April 1974, this area came under the auspices of Northumbria Police.
