cupeno.org is a nonprofit organization dedicated to serving the Agua Caliente Tribe of Cupeño Indians, an Indigenous people whose ancestral homeland lies in the mountains and valleys of Southern California. Our mission is rooted in the protection, revitalization, and continuation of Cupeño identity—an identity shaped by deep cultural knowledge, a unique language, and a history marked by both resilience and displacement.
For generations, the Cupeño people have carried forward traditions that reflect a profound relationship with the land, community, and spiritual practice. However, like many Native nations, the tribe has faced significant challenges, including forced removal from their homeland in 1903 and the long-term impacts of federal policies that disrupted cultural continuity. In response to these ongoing challenges, cupeno.org works to strengthen cultural foundations and ensure that future generations inherit a living, thriving heritage.
A central focus of our efforts is language preservation. The Cupeño language—one of the Takic languages of Southern California—is critically endangered, and revitalizing it is essential to maintaining cultural identity. Through educational programs, community classes, archival work, and intergenerational learning, we support the return of the language to everyday life.
We are equally committed to cultural preservation, including traditional arts, oral histories, ceremonial practices, and the protection of ancestral knowledge. By documenting, teaching, and celebrating these traditions, we help reconnect tribal members with the wisdom of their ancestors.
Another core priority is the reinstatement of federal acknowledgment, a vital step toward restoring the tribe’s sovereign status and ensuring access to the rights, protections, and resources that were historically denied. This work involves research, advocacy, community organizing, and the careful preservation of historical records that demonstrate the tribe’s continuous existence.
Through all these efforts, cupeno.org stands as a guardian of heritage and a catalyst for cultural renewal, working to ensure that the Cupeño people’s story continues with strength, dignity, and visibility for generations to come.

In the Cupeño native language, they call themselves Kuupangaxwichem, which means “people who slept here."
