José Joaquín de la Santísima Trinidad Moraga (August 22, 1745 – 1785) (usually known as José Joaquín Moraga) was an early explorer to upper Las Californias. Moraga is also known as the founder of El Pueblo de San José de Guadalupe, later known as San Jose, California.
José Joaquín Moraga was born on August 22, 1745 at Mission Los Santos Ángeles de Guevavi in the northern frontier region of the Viceroyalty of New Spain (in present day Arizona).
He is credited with building the Presidio of San Francisco, after the site was selected by Juan Bautista de Anza in 1776.
Moraga founded the Pueblo of San José on orders from Antonio María de Bucareli y Ursúa, Spanish Viceroy of New Spain. The city was founded in honor of Saint Joseph on November 29, 1777 as the first town in the Spanish colony of Nueva California, which later became Alta California. The city served as a farming community to support the Presidio of San Francisco and the Presidio of Monterey.
Moraga died in Yerba Buena (San Francisco) in 1785, and was buried at Mission San Francisco de Asís (Mission Dolores) cemetery in 1790.
Moraga's son Gabriel Moraga was also a Spanish soldier in California and led expeditions exploring the San Joaquin Valley.
The town of Moraga, California is named after Joaquin Moraga, the grantee of Rancho Laguna de los Palos Colorados and grandson of José Joaquín Moraga. His home, the Moraga Adobe, is located there.
