Atrium Health, formerly Carolinas HealthCare System, is a hospital network with more than 70,000 employees. It operates 42 hospitals, six freestanding emergency departments, over 30 urgent care centers, and more than 1,500 care locations in the American states of North Carolina and Georgia. It provides care under the Atrium Health Wake Forest Baptist name in the Winston-Salem, North Carolina, region and Atrium Health Navicent in Georgia. Atrium Health offers pediatric, cancer, and heart care, as well as organ transplants, burn treatments and specialized musculoskeletal programs.

Legally, Atrium Health is The Charlotte-Mecklenburg Hospital Authority, a municipal hospital authority established under North Carolina's Hospital Authorities Act (North Carolina General Statutes chapter 131E, part 2). The authority is governed by a self-perpetuating board of commissioners which nominates new commissioners to fill its own vacancies; the chair of the Mecklenburg Board of County Commissioners can approve or veto those nominations but not make nominations of her own.
