Major Hospital Systems

Long Island’s hospitals are organized primarily within several large healthcare systems. Northwell Health operates academic, community, pediatric, and behavioral health hospitals across the island. Catholic Health operates six hospitals, including St. Francis Hospital & Heart Center and Good Samaritan University Hospital. NYU Langone Health operates major hospital campuses in Mineola and Patchogue, while Stony Brook Medicine operates hospitals in Stony Brook, Southampton, and Greenport.

Emergency and Specialized Care

For a life-threatening emergency, call 911 rather than relying on an online directory. The closest emergency department is often the appropriate destination for immediate care, but ambulance crews and physicians may direct patients to a hospital equipped for a particular need, such as trauma care, pediatric emergencies, cardiac intervention, stroke treatment, burn care, high-risk maternity care, or psychiatric services. Not every hospital offers every specialty, and some facilities listed below focus primarily on children, behavioral health, cardiovascular care, or other specialized services.

It includes general hospitals, academic medical centers, children’s hospitals, public hospitals, and selected specialty hospitals. Outpatient offices, urgent-care centers, rehabilitation facilities, nursing homes, and standalone medical practices were not included.

The directory is not a ranking and does not evaluate medical quality or recommend a particular facility. Hospital names, ownership, campus relationships, services, trauma designations, and contact information can change. Readers should verify current information directly with the hospital or healthcare system. Map coordinates are based on published hospital addresses and are checked before being added to the production map.
