Trent Lock (otherwise Trentlock) is located south of Long Eaton, on the borders of Derbyshire, Leicestershire and Nottinghamshire in the United Kingdom. The area is a major canal navigation junction, where the River Soar and Erewash Canal can reach the Trent and Mersey Canal by way of the River Trent and adjacent Cranfleet Cut.
Immediately to its north-east is Trent Junction, a similarly important five-way meeting point in the national railway system.
