Chellis Glendinning (1947–) is a writer and activist for social change. She is considered a pioneer and noted contributor in the field of ecopsychology. Her writings often focus on the interlace of the personal with the political and a critique of mass technological society as contrasted by nature-based cultures, and her interests include bioregionalism, feminism, and indigenous rights.

Glendinning has published nine books, including Off the Map: An Expedition Deep into Empire and the Global Economy (New Society Publishers, 2002) and Chiva: A Village Takes on the Global Heroin Trade (New Society Publishers, 2005), both of which won National Federation of Press Women book awards. Her storied lifetime of activism is recounted through portraits of her peers in In the Company of Rebels: A Generational Memoir of Bohemians, Deep Heads, and History Makers (New Village Press, 2019). 

Glendinning has also published hundreds of articles and essays in journals, magazines, and newspapers such as Guernica, Orion, CounterPunch, Alternet, Salon, Los Tiempos, Le Monde Diplomatique, and Nueva Crónica. She is Editor-on-the-Lam at Journal of Wild Culture. Archives of her life, times, and work are housed at the Labadie Collection of the University of Michigan. She lives in Chuquisaca, Bolivia.
