Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.

Haplogroup I most likely arose in Europe,[1][2] with it so far found in Palaeolithic sites throughout Europe, but not outside it.[3] It diverged from common ancestor IJ* about 43,000 years ago.[4] Early evidence for haplogroup J has been found in the Caucasus and Iran.[3] In addition, living examples of the precursor Haplogroup IJ* have been found only in Iran, among the Mazandarani and ethnic Persians from Fars.[5] This may indicate that IJ originated in South West Asia.

The oldest example found was originally that of Paglicci133 from Italy, which is at least 31,000 years old,[6] however, in a later study this was changed, and instead Dolní Věstonice (DV14) from the Czech Republic was reported as the oldest, being at least 30,800 years old.[7]

Haplogroup I has been found in multiple individuals belonging to the Gravettian culture. The Gravettians expanded westwards from the far corner of Eastern Europe, likely Russia, to Central Europe. They are associated with a genetic cluster that is normally called the Věstonice cluster.[8][9][10]
