Tribal Acknowledgment

We acknowledge that the unceded territory of California is home to nearly 200 tribal nations. 

We acknowledge and honor the original inhabitants of our various regions. The land that surrounds us is part of who we are presently, and it reflects our histories. San Diego County is home to four federally recognized and resilient tribal nations of the Kumeyaay/Diegueño, Payómkawichum (Quechnajuichom/Luiseño and Acjachemen/Juaneño), Kuupiaxchem/Cupeño, and Cahuilla people.

It is also important to acknowledge that this land remains the home to the 18 federally recognized bands of the Barona, Campo, Capitan Grande, ‘Ewiiaapaayp (Cuyapaipe), Inaja-Cosmit, Jamul Indian Village, Laguna, La Jolla, La Posta, Los Coyotes, Manzanita, Mesa Grande, Pala, Pauma, Rincon, San Luis Rey, San Pasqual, Santa Ysabel, Sycuan, and Viejas Indian reservations.
