The Teduray people are a Filipino ethnic group. They speak the Tiruray language.
The Tiruray (Teduray) culture was studied at length in the 1960s by anthropologist Stuart A. Schlegel. Schlegel spent two years as a participant/observer among a group who lived in and was sustained by the rainforest. He was profoundly moved by the egalitarian society he witnessed, and went on to write several books and papers on the subject, including "Wisdom of the Rainforest: The Spiritual Journey of an Anthropologist."
