Cesar E. Chavez National Monument, Farm workers movement memorial in Keene, California, United States.

César E. Chávez National Monument, also called Nuestra Señora Reina de la Paz, is a 116-acre district in Keene among the Tehachapi Mountains. Its buildings follow Bungalow, Craftsman, Mission and Spanish Revival styles, with architects F. H. Oldershaw and Robert Porteus recorded for the property. A visitor center and memorial garden are open, while some areas remain closed because Chávez family members and UFW staff still use them.

The property began as worker housing for a quarry, then served as the Stony Brook Sanatorium in the early 1900s. The United Farm Workers acquired it in the early 1970s, and César Chávez lived and directed the union from La Paz until his death in 1993. President Barack Obama proclaimed the national monument on October 8, 2012.

The site preserves César Chávez's office with original furnishings, showing the importance of the Latino civil rights movement and the fight for agricultural worker rights in America. Visitors can see how this space became the headquarters of a national organizing movement.

The monument can be visited during regular opening hours, though some areas remain reserved for ongoing organizational work. Plan enough time to explore the visitor center and walk through the memorial gardens.

The property began as a quarry workers' housing site and later served as the Stony Brook Sanitorium, a tuberculosis facility, in the early 1900s before the UFW bought it in the early 1970s. Chávez's grave lies in the memorial garden beside that of his wife, Helen Fabela Chávez.
