The London, Tilbury and Southend Railway (LT&SR) 2100 Class was a class of 4-6-4T steam locomotives. Eight were built in 1912, the year the Midland Railway took over the LT&SR, to the design of Robert Harben Whitelegg. Hence, they were numbered in the Midland numbering system as 2100–2107, and none received a name. The Midland gave them the power classification 3P. All subsequently passed into LMS ownership in 1923. They were all withdrawn 1929–1934, and all were scrapped.
