The London, Midland and Scottish Railway (LMS) Ivatt Class 2 2-6-2T is a class of light 'mixed-traffic' steam locomotive introduced in 1946. The LMS had various elderly tank engines and the operating department required a new small class 2 locomotive to replace them. Noting that the Great Western Railway 4500 and 4575 Classes of 2-6-2T ('Prairie') had been successful, George Ivatt designed the new engine type incorporating self-emptying ashpans and rocking grates which were labour-saving devices. A tender version, the Ivatt Class 2 2-6-0 was also produced. The LMS classified them as 2P, but BR preferred the classification 2MT.

The class were withdrawn between 1962 and 1967. Four engines have survived to preservation.
