The LSWR 135 class was a class of 4-4-0 express steam locomotives designed by William Adams for the London and South Western Railway and introduced in 1880.

They were built by Beyer, Peacock and Company and received LSWR numbers 135–146.

[1] Twelve locomotives were purchased and placed in service between November 1880 and January 1891.

Only two were still in service to pass to the Southern Railway in 1923, but they were withdrawn the following year.
