UC Davis Medical Center (UCDMC) is part of UC Davis Health and a major academic health center located in Sacramento, California. It is owned and operated by the University of California as part of its University of California, Davis campus. The medical center sits on a 142-acre (57 ha) campus (often referred to as the Sacramento Campus to distinguish it from the main campus in nearby Davis) located between the Elmhurst, Tahoe Park, and Oak Park residential neighborhoods. The site incorporates the land and some of the buildings of the former Sacramento Medical Center (which was acquired from the County of Sacramento in 1973) as well as much of the land (and two buildings) previously occupied by the California State Fair until its 1967 move to a new location.

Sacramento is the capital city of the U.S. state of California and the county seat of Sacramento County. Located at the confluence of the Sacramento and American Rivers in Northern California's Sacramento Valley, Sacramento's 2020 population of 524,943 makes it the fourth-most populous city in Northern California, sixth-most populous city in the state, and the ninth-most populous state capital in the United States. Sacramento is the seat of the California Legislature and the Governor of California.
