CFU-GM (Colony Forming Unit–Granulocyte–Macrophage[a]), also known as granulocyte–macrophage progenitor (GMP), is a colony forming unit.

It is the precursor for monoblasts and myeloblasts.

Production is stimulated by granulocyte macrophage colony-stimulating factor (GM-CSF).

There is some controversy over which granulocytes derive from CFU-GM.
