Tana Toraja Regency (Indonesian for Torajaland or Land of the Toraja, abbreviated Tator) is a regency (kabupaten) of South Sulawesi Province of Indonesia, and home to the Toraja ethnic group. The local government seat is in Makale, while the center of Toraja culture is in Rantepao. But now, Tana Toraja has been divided to two regencies that consist of Tana Toraja with its capital at Makale and North toraja with its capital at Rantepao.

The Tana Toraja boundary was determined by the Dutch East Indies government in 1909. In 1926, Tana Toraja was under the administration of Bugis state, Luwu. The regentschap (or regency) status was given on 8 October 1946, the last regency given by the Dutch. Since 1984, Tana Toraja has been named as the second tourist destination after Bali by the Ministry of Tourism, Indonesia. Since then, hundreds of thousands of foreign visitors have visited this regency. In addition, numerous Western anthropologists have come to Tana Toraja to study the indigenous culture and people of Toraja.
