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".
