Ahir or Aheer is a community in India, most members of which identify as being of the Indian Yadav community because they consider the two terms to be synonymous. The Ahirs are variously described as a caste, a clan, a community, a race and a tribe.
The traditional occupations of Ahirs are cattle-herding and agriculture. They are found throughout India but are particularly concentrated in the northern area. Apart from India, Ahirs have significant population in Nepal, Mauritius, Fiji, South Africa and the Caribbean especially Guyana, Trinidad and Tobago, and Suriname. In Mauritius and Caribbean they are mostly the descendants of settlers who arrived between the 19th and 20th centuries from the former pre-partitioned sub-continent of India during the time of the British Raj.
Ahirs in India are known by numerous other names, including Gauli and Ghosi or Gop in North India. In Gujarat and South India as Ayar, Golla and Konar. Some in the Bundelkhand region of Uttar Pradesh are known as Dauwa. In Haryana, Ahirs are sometimes referred as Rao/Rao Sahab. They have more than 20 sub-castes.
