Nicole Horseherder is Diné (Navajo) and executive director of Tó Nizhóní Ání (“Beautiful Water Speaking”) which works to protect the waters of Dinétah, her tribal homeland in the Black Mesa region (Dzi? Yijiin) of Navajo Nation.

Nicole’s climate advocacy work has been widely featured on NPR, PBS, and elsewhere.  In 2019, Nicole was recognized by Elle magazine as one of the world’s leading female voices in the fight against anthropogenic climate change and in 2021 Time magazine heralded her water rights advocacy on the behalf of her tribe.

Nicole holds a masters of arts in linguistics from the University of British Columbia, Vancouver, British Columbia, Canada. Nicole and her family are active members of the Native American Church of Navajo Land. Nicole’s grandfather is one of the first facilitators of the peyote ceremony when it was still illegal to possess the medicine. Nicole has continued to follow the traditions of her people — traditions which inform her work as an activist. 

Nicole believes in the importance of preserving and protecting traditional cultural knowledge including peyote, especially when it comes to sharing traditional knowledge with European colonizers and non-Indians.
