Hennepin County Medical Center (HCMC), is a Level I trauma center in Minneapolis, Minnesota, the county seat of Hennepin County. The primary 455-bed facility is on six city blocks across the street from U.S. Bank Stadium, with neighborhood clinics in the Minneapolis Whittier and East Lake neighborhoods, and the suburban communities of Brooklyn Center, Brooklyn Park, Golden Valley, St. Anthony and Richfield. A new clinic in the North Loop neighborhood downtown opened in 2017. Some patients come a long distance to be treated at HCMC because of the recognized trauma surgery specialists, transplant services, stroke specialists, advanced endoscopy/hepatobilliary center, and hyperbaric oxygen chamber. A new outpatient clinic building opened in 2018. In March 2018, the provider that operates HCMC was rebranded as Hennepin Healthcare. However, the hospital retained the name HCMC.
The original hospital building, established in 1887 as Minneapolis City Hospital, before being referred to as "General Hospital" or "City Hospital," sat a block from its current main location. Ownership was transferred to the county in 1964, when it was renamed Hennepin County General Hospital. The hospital took its current name in 1974. By the late 1960s, the hospital was a disorganized patchwork of buildings, leading to the decision to clear and rebuild the facility. The current hospital facility was completed in 1976 and renamed Hennepin County Medical Center, following a $25 million bond passed by voters in 1969. The hospital expanded in 1991 when the adjacent Metropolitan-Mount Sinai Medical Center closed. It gained Level I trauma center status in 1989, the first such site in the state. The hospital underwent a governance change in January 2007, which created a new governing entity with greater autonomy from the county government. The hospital's public mission did not change, but this transition was made to ensure the long-term viability of the hospital. In 2012 the hospital partnered with NorthPoint Health and Wellness Center, Metropolitan Health Plan, and Hennepin County's Human Services and Public Health Department to form an accountable care organization called Hennepin Health. By February 2013, Hennepin Health had enrolled 6,000 clients.
In 2015, the Hennepin County Board allocated $192 million for a new outpatient center which features multiple clinics across from the HCMC entrance. The building opened in March 2018. In 2018, HCMC became Hennepin Healthcare.

It has independent fellowships in geriatrics, critical care medicine, sleep medicine and nephrology.
NASA astronaut Kjell Lindgren is a graduate of the Emergency Medicine residency program (2002-2005). He was selected to NASA's 20th astronaut class in 2009, and spent 141 days in space on Expedition 44/45 in 2015. 
Students from UCIMED, a medical school in Costa Rica, are given the opportunity to complete an internship at the hospital. The initiative started thanks to an agreement signed on February 2006. Many of the students from UCIMED go on to work as residents at HCMC.
