San Bernardino Ranch is a historic ranch house in the southern San Bernardino Valley near the San Bernardino National Wildlife Refuge in extreme southeast Cochise County, Arizona, United States. It is significant for its association with the beginning of cattle ranching in southern Arizona and northern Mexico. The ranchland and valley are part of the headwaters region of the Yaqui River.
The site is also known as the Slaughter Ranch, for it was the home of the Old West lawman John Horton Slaughter from the 1880s until his death in 1922. In 1911, during the conflict known as the Border War, a United States Army camp was established at the ranch and was called Camp San Bernardino Ranch, or the Slaughter Ranch Outpost.
The site was declared a National Historic Landmark in 1964 for its association with Slaughter. Today the compound includes the preserved ranch house, wash house, icehouse, granary, and commissary. Much of it is set up as a museum known as the Johnson Historical Museum of the Southwest.
