The London Midland and Scottish Railway (LMS) Fowler 3F 0-6-0T is a class of steam locomotive, often known as a Jinty. They represent the ultimate development of the Midland Railway's six-coupled tank engines. They could reach speeds of up to 60 mph.

Design of this class was based on rebuilds by Henry Fowler of the Midland Railway 2441 Class introduced in 1899 by Samuel Waite Johnson. These rebuilds featured a Belpaire firebox and improved cab. 422 Jinties were built between 1924 and 1931; this class was just one of the Midland designs used on an ongoing basis by the LMS.

The first withdrawals started in 1959 and by 1964 half had been withdrawn. The final five survived until 1967, with a further one, 47445 continuing with the National Coal Board. Thanks to their large numbers, renowned performance and late withdrawals, nine of these engines have been preserved, along with a spare set of frames and a boiler (from 47564). Many were restored within a few years of leaving the scrap heap, and most have a further working life ahead of them. All have steamed in preservation, with the exception of 47445.
