The Bloch MB.120 was a French three-engine colonial transport aircraft built by Société des Avions Marcel Bloch during the 1930s.

It was an all-metal high-wing cantilever monoplane.

Ten production aircraft were produced, six for civil use and four for the French Air Force.

The aircraft entered operation in 1934 for Air Afrique, which was a new airline set up by the French government on 11 May 1934 to provide service between the French African territories.

Both the civil and military aircraft served only in French Africa.
