London Midland was a train operating company in England, owned by Govia, which operated the West Midlands franchise between 2007 and 2017.

London Midland operated local services in the West Midlands and surrounding areas through their City sub-brand. They also provided long distance and commuter services on the West Coast Main Line through the Express sub-brand from London Euston to and from the West Midlands, Hertfordshire, Buckinghamshire, Bedfordshire, Northamptonshire, Staffordshire and Cheshire.
