The Great Northern Railway J4 Class was a class of 322 0-6-0 steam locomotives, introduced in 1882 designed by Patrick Stirling for goods traffic. Just over half of these were rebuilt by Nigel Gresley to a design by Henry Ivatt between 1912 and 1929.

The Stirling and Ivatt J3 & J4 (GNR Classes J4 & J5) 0-6-0 Locomotives. The history of the LNER J3 and J4 locomotives is complicated, and starts with Stirling's Great Northern Railway (GNR) Class J7. Thirty five J7s were built between 1867 and 1873.

The following is a list of locomotives built for the Great Northern Railway. As is customary, engine classes are organized according to the man who was locomotive superintendent when the class was introduced, and to whom the design is often attributed. Six men held this post during the existence of the Great Northern Railway.
