The NMBS/SNCB Type 29 was a class of 2-8-0 steam locomotives built between 1945 and 1946.

The class was ordered and used to help revive the operations of the National Railway Company of Belgium (NMBS/SNCB) following World War II.

The locomotives were built in Canada and the United States, and supplied to Belgium under the auspices of what later became known as the Marshall Plan.
