Hindu ( pronunciation (help·info); Devanagari:हिंदू) refers to an identity associated with the philosophical, religious and cultural systems that are indigenous to the Indian subcontinent. As used in the Constitution of India, the word "Hindu" is also attributed to all persons professing any Indian religion (i.e. Hinduism, Jainism, Buddhism or Sikhism). In common use today, it refers to an adherent of Hinduism.

With more than a billion adherents, Hinduism is the world's third largest religion. The vast majority of Hindus, approximately 940 million, live in India. Other countries with large Hindu populations include Nepal, Bangladesh, Sri Lanka, Mauritius, Suriname, Guyana, Trinidad & Tobago, Fiji and the island of Bali.

The word Hindu is derived from the Sanskrit word Sindhu, first mentioned in the Rig Veda, was the historic local appellation for the Indus River in the northwestern part of the Indian subcontinent.

The Brihaspati Agama says:

The usage of the word Hindu was further popularized for Arabs and further west by the Arabic term al-Hind referring to the land of the people who live across river Indus and the Persian term Hindū referring to all Indians. By the 13th century, Hindustān emerged as a popular alternative name of India, meaning the "land of Hindus".
