Haplogroup D-Z27276 also known as Haplogroup D1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup D1, one of the descendants of Haplogroup D. The other is D-M55 which is only found in Japan.

This group is found in about 46.6% Tibetan people.[2] It branched off D-M55 35,000-40,000 years before present or already 53,000 years before present.[1][3]

One sample of a subgroup of D-Z27276 was also found among ancient samples of the Koban culture between Russia and Georgia.[4]
