In human genetics, Haplogroup R1b1b2a1a1 (U106), is a Y-chromosome haplogroup which is a subdivision of haplogroup R1b defined by the presence of the marker U106, also known as S21 and M405. It appears to represent over 25% of R1b in Europe.

Nomenclature
The subclade was first discovered by EthnoAncestry in 2006 and given the nomenclature of R1b1c9. In May 2008 it was given the name R1b1b2g in the 2008 Karafet nomenclature. In October 2008 it was renamed to R1b1b2a1 according to the 2008 FamilyTreeDNA YDNA haplogroup nomenclature.

Subclades
This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree and subsequent published research as summarized by ISOGG.
