Pablo Tac (1822–1841) was a Luiseño (Quechnajuichom also spelt "Qéchngawichum") Indian and indigenous scholar who provided a rare contemporary Native American perspective on the institutions and early history of Alta California. He created the first writing system for Luiseño, and his work is the "only primary source of Luiseño language written by a Luiseño until the twentieth century."Tac was born of Luiseño parents at Mission San Luis Rey de Francia and attended the Mission school.
