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.Michael F Hammer; Tatiana M Karafet; Hwayong Park; Keiichi Omoto; Shinji Harihara; Mark Stoneking; Satoshi Horai (2006). “Dual origins of the Japanese: common ground for hunter-gatherer and farmer Y chromosomes”.

Diffusion of existing subtypes of C-M8 is estimated to have begun about 12,000 years ago.Hammer MF, Karafet TM, Park H et al. (2006).

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