In human genetics, Haplogroup R-M167 is a Y-chromosome haplogroup which is a subdivision of haplogroup R1b defined by the presence of the marker M167, also known as SRY2627.

The first author to test for this marker (long before current haplogroup nomenclature existed) was Hurles in 1999, who tested 1158 men in various populations. He found it relatively common among Basques (13/117: 11%) and Catalans (7/32: 22%). Other occurrences were found among other Spanish, Béarnais, other French, British and Germans.
In 2000 Rosser et al., in a study which tested 3616 men in various populations also tested for that same marker, naming the haplogroup Hg22, and again it was found mainly among Basques (19%), in lower frequencies among French (5%), Bavarians (3%), Spanish (2%), Southern Portuguese (2%), and in single occurrences among Romanians, Slovenians, Dutch, Belgians and English.
In 2001 Bosch described this marker as H103, found in 5 Basques and 5 Catalans. However a study in 2005 of Spanish Basques found lower levels of this haplogroup than those recorded in Basques by the earlier studies - only four samples out of the 168 tested.
In 2008 a study by Adams and colleagues covered the whole of the Iberian Peninsula. It found the highest levels of this haplogroup in Catalonia. In same year a study by López-Parra and colleagues concentrated on the populations of the Spanish Pyrenees. They discovered a high levels of this haplogroup in the central and eastern Pyrenees. The highest level so far discovered (48%) was found in the Val d'Aran, Catalonia.
In a larger study specifically of Portugal in 2006, with 663 men tested, Beleza et al. showed low levels of this haplogroup ( described in the paper as R1b3f) in all the major regions, from 1.5%-3.5%. Breaking the results down to district, only Lisboa (at 5.7%) had over 5%.
A 2012 study by Martinez-Cruz et al. found the following percentages of SRY2627: 7% in the three French departments of the Pays de Basque, 16% in Bearn, 14% in Bigorre, 7% in Chalosse, 6% in the Basque regions of Spain, 15% in La Rioja, and 19% in northern Aragon.
