Haplogroup J-M267, also commonly known as Haplogroup J1, is a subclade (branch) of Y-DNA haplogroup J-P209 (commonly known as haplogroup J) along with its sibling clade haplogroup J-M172 (commonly known as haplogroup J2). (All these haplogroups have had other historical names listed below.^{[Phylogenetics 1][Phylogenetics 2]})

Men from this lineage share a common paternal ancestor, which is demonstrated and defined by the presence of the single nucleotide polymorphism (SNP) mutation referred to as M267, which was announced in (Cinnioğlu 2004). This haplogroup is found today in significant frequencies in many areas in or near the Arabian Peninsula and Western Asia. Out of its native Asian Continent, it is found at very high frequencies in Sudan. It is also found at very high but lesser extent in parts of the Caucasus, Ethiopia and parts of North Africa and amongst most Levant peoples, including Jewish groups, especially those with Cohen surnames. It can also be found much less commonly, but still occasionally in significant amounts, in parts of southern Europe and as far east as Central Asia.^{[citation needed]}
