Haplogroup C-M8 also known as Haplogroup C1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup C1a, one of the descendants of Haplogroup C-M130.

It has been found in about 6% (2.3% to 16.7%) of modern males sampled in Japan and has been considered to be a Y-DNA haplogroup descended from Jōmon people.[5][6] Elsewhere, it has been observed among academic studies only in one individual in a sample collected on Jeju Island of South Korea[7] and in commercial testing in one individual who has reported an origin in Liaoning province of China and one individual who has reported an origin in Seoul, South Korea.[8]

The MRCA with its sister haplogroup C-V20 dates back to 40,000[1] to 50,000[2] years ago. Diffusion of existing subtypes of C-M8 is estimated to have begun about 12,000 years ago.[3]

C1a1 is found in the Jōmon people and are linked to the Jomon people who came from the south route.
