Haplogroup O-M122 (also known as Haplogroup O2 (formerly Haplogroup O3)) is an Eastern Eurasian Y-chromosome haplogroup. The lineage ranges across Southeast Asia and East Asia, where it dominates the paternal lineages with extremely high frequencies. Certain subclades also have a significant presence in Central Asia, South Asia (e.g. Nepal, Northeast India), and Oceania.
This lineage is a descendant haplogroup of haplogroup O-M175.
