In human genetics, Haplogroup L2 is a human mitochondrial DNA (mtDNA) haplogroup.

Haplogroup L2 is native to sub-Saharan Africa, where it is present in approximately one third of all people. It is believed to have arisen between 87,000 to 107,000 years ago.^[1]

L2 has four main subgroups: L2a, L2b, L2c, and L2d.

The most common L2 subgroup, L2a, is also the most common haplogroup among African Americans.
