Finsbury Park TMD was a railway traction maintenance depot situated in London, England.

It was the first purpose built main line diesel locomotive depot opened in England and it was fully commissioned in April 1960.

Additionally there were five roads of stabling in Clarence Yard, which was nearest to the main running lines.

[3] The site is now covered in residential flats which can be seen to the south-west of Finsbury Park station.

Following the closure of Kings Cross Top Shed and the withdrawal of steam locomotives, much of the traction power for express passenger workings on the East Coast Main Line was taken over by Class 55 Deltic diesel locomotives.
