The Manchukuo National Railway Tehosa class steam locomotives were a class of 4-6-0 passenger steam locomotives operated by the Manchukuo National Railway.
Originally built for the South Manchuria Railway (Mantetsu), they later transferred to the MNR.
The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten-Wheeler".
Together with the Sorisa class, these five passenger locomotives built by Beyer, Peacock & Company in 1912 were the first locomotives Mantetsu ordered from England.
They were taken over by the Republic of China Railway in 1945, but their subsequent fate is unknown.
