The Mammal Neogene zones or MN zones are system of biostratigraphic zones in the stratigraphic record used to correlate mammal-bearing fossil localities of the Neogene period of Europe. It consists of seventeen consecutive zones defined through reference faunas, well-known sites that other localities can be correlated with. MN 1 is the earliest zone, and MN 18 is the most recent. The MN zones are complementary with the MP zones in the Paleogene.
