Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479).

Males carrying R-M173 in modern populations appear to comprise two subclades: R1a and R1b, which are found mainly in populations native to Eurasia (except East and Southeast Asia). R-M173 contains the majority of representatives of haplogroup R in the form of its subclades, R1a and R1b (Rosser 2000, Semino 2000).
