In human genetics, Haplogroup J-M172 or J2 is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-P209. Haplogroup J-M172 is found in Western Asia, Central Asia, South Asia, Europe and North Africa, but it is usually associated with Northwest Asia. It is thought that J-M172 might have originated between the Caucasus Mountains, Mesopotamia and the Levant.

It is further divided into two complementary clades, J-M410 and J-M12 (M12, M102, M221, M314).

The date of origin for haplogroup J-M172 was estimated by Batini et al in 2015 as between 19,000 and 24,000 Years Before Present (YBP).Samino et al in 2004 dated the origin of the parent haplogroup, J-P209, to between 18,900 and 44,500 YBP.

It is likely that J2 men had settled over most of Anatolia, the South Caucasus and Iran by the end of the Last Glaciation 12,000 years ago.

Zalloua and Wells 2004 and al-Zaheri 2003 uncovered the earliest known migration of J2, from Sumeria to Canaan. In 2001, Nebel et al. found that, "According to Underhill et al. (2000), Eu 9 (H58) evolved from Eu 10 (H71) through a T→G transversion at M172 (emphasis added)," and that in today's populations, Eu 9 (the post-mutation form of M172) is strongest in the Caucasus, Asia Minor and the Levant, whilst Eu 10 becomes stronger and replaces the frequency of Eu 9 as one moves south into the Arabian Peninsula, so that Eastern Europeans from the Caucasus met with Arabs near and between Mesopotamia (formerly Sumeria) and the Negev Desert, as "Arabisation" spread from Arabia to the Levant and Turkey, as well as many peoples (e.g. Jews, Armenians, Lebanese) having returned from diasporas.
