Colney Street is a hamlet in the English county of Hertfordshire.
It lies on the A5183 road, this was formerly the A5 road and, before that, Roman Britain's Watling Street. In addition its northern boundary is delineated by the M25 motorway. These location advantages have led to it becoming a primarily industrial and business area.
Colney Street forms part of the civil parish of St Stephen in the district of St Albans.
