The South African Railways Class MF 2-6-6-2 of 1911 was a steam locomotive from the pre-Union era in Transvaal. In 1911, the Central South African Railways placed nine Mallet articulated compound steam locomotives with a 2-6-6-2 wheel arrangement in service. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class MF. Five more of these locomotives were delivered in November 1911 and were numbered directly onto the South African Railways roster.
