The Karajá, also known as Iny, are an indigenous tribe of the Brazilian Amazon. Earlier in the 20th century, there were 45,000 Karajá. As of 1999, there were 2500-3000 Karajá. In 2010, there were 3,198 Karajá.

Karajá people live in a 180-mile-long area in central Brazil, in the Goiás, Mato Grosso, Pará, and Tocantins provinces. They currently reside in 29 villages in the Araguaia River valley, near lakes and tributaries to the Araguaia and Javaés Rivers, and the Ilha do Bananal.

They speak the Karajá language, which is part of the Macro-je language family. Dialects are North Karaja, South Karaja, Xambioá, and Javaé. There are distinct male and female forms of speech; one of the principal differences is that men drop the sound /k/, which is pronounced by women.

Although they are known as one of Brazil's poorest tribes, they are self-sufficient. Their livelihood is based upon agriculture and craft work. Crops are diverse and include bananas, beans, manioc, maize, peanuts, potatoes, watermelons, and yams. Fishing is also highly important, as is hunting. Ceramics dolls are commonly made for export.
