Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. It is the most common macro-haplogroup in West Eurasia.
Haplogroup R is a descendant of macro-haplogroup N. Among its descendant haplogroups are B, U (and thus K), F, R0 (and thus HV, H, and V), and JT (the ancestral haplogroup of J and T).
As of June 2009, the most recent study dates the origin of haplogroup R to 66.8kya (thousand years ago) with a 95% confidence interval of 52.6–81kya.
South Asia lies on the way of earliest dispersals from Africa and is therefore a valuable well of knowledge on early human migrations. The analysis of the indigenous haplogroup R lineages in India points to a common first spread of the root haplotypes of M, N, and R along the southern route some 60–70 kya.
Haplogroup R has wide diversity and antiquity among varied ethnic status and different language families in South Asia. In Indian western region among the various castes and southern region among the tribes show higher haplogroup diversity than the other regions, possibly suggesting their autochthonous status.
Haplogroup R and its descendants are distributed all over Europe, North Africa, the Horn of Africa, the Near East, the Indian Subcontinent, Oceania and the Americas.
The basal R* clade is found among the Socotri (1.2%), as well as in Northeast Africa (1.5%), the Middle East (0.8%), the Near East (0.8%), and the Arabian peninsula (0.3%).

It is also present in low frequency among the Dravidian and Indo-European speaking family R8a: Found mainly in Orissa and Andhra Pradesh (India).R8b: In Orissa, Gujarat, Andhra Pradesh (India).R9 (16304)R9b: It appears mostly in Southeast Asia. Found all over Indonesia, in Indochina, Malaysia, in Aboriginal Malays like Semelai at 28% and Temuan 21%.(249d)R9c: All over the Malay Archipelago and Taiwan. Mainly in Batak (Palawan) at 58% and Alor (Indonesia) at 11%.F: Fairly common in East Asia and Southeast Asia. Higher frequencies occur in some areas like Nicobar at 50% and Arunachal Pradesh 31% (India), and Shors people from Siberia at 44%. There is also an important frequency in Taiwanese aborigines, Guangdong (China), Maluku (Indonesia), Thailand and Vietnam.R11'B (16189)R11: Found in China, mainly in Lahu people from Yunnan at 12.5%. Also in Japan and Rajasthan (India).BB4: It is found often in East Asia, Southeast Asia, Polynesia, Melanesia, Micronesia, Madagascar and Indigenous peoples of the Americas.B5: Spread in East Asia and Southeast Asia.R24: Found in Philippines.R12'21R12: Found in Australia.R21: In indigenous peoples of Malaysia like Jahai Negritos at 63% and Senoi 37%.R14: Found in Papua New Guinea and in Austronesian speakers of East Timor and Lembata.R22 or R12: Very frequent in the Shompen (10/29 = 34.5%). Elsewhere found mainly in south-central Indonesia (11.4% Mataram, 8.0% Waingapu, 7.3% Bali, 1.9% Borneo) and in Cham of Bình Thuận, Vietnam (7/168 = 4.2%), with singleton or sporadic occurrences in Thailand, Sumatra, Java, Sulawesi, and Alor.R23: Small clade found in Bali and Sumba (Indonesia).R30R30a: Found in Andhra Pradesh, Uttar Pradesh (India), in the Tharu people from Nepal and Sinhalese people from Sri Lanka.R30b: Found in Punjab.R30* (1598, 16189): Found in Punjab, Nepal and Japan.R31R31a: In Brahmins from Uttar Pradesh and Rajputs from Rajasthan (India).R31b: In Reddys from Andhra Pradesh (India).P: It is characteristic of Sahul.
