Cardiff Canton TMD is a diesel locomotive Traction Maintenance Depot in Cardiff, Wales. Its depot code is CF. It is operated by Arriva Trains Wales. The depot is used by Arriva Trains Wales fleet and some Cross Country class 170s.

In steam days the depot was called Cardiff Canton and its shed code was 86C. It was built in 1882 as the main maintenance base for the South Wales Railway and the major Welsh engineering base for the Great Western Railway (GWR). After nationalisation in 1948 it was a heavy overhaul base for British Railways.

After privatisation in the mid-1990s the depot became a joint Arriva Trains Wales and English Welsh & Scottish facility. The EWS depot closed as a maintenance centre from 10 December 2005, but EWS' successor DB Cargo UK still uses the depot for long term storage and occasional stabling.
