Lewis County General Hospital (LCGH) is a Short Term Acute Care facility in Lowville, New York serving its eponymous county both for medical service and as its largest employer. LCGH is part of "Lewis County Health System".

In April 2020, due to the Covid epidemic, elective surgeries were curtailed.

The hospital is actively recruiting and hopes to resume the service in spring 2023. In the interim, pre-natal care is provided at the Women's Health Clinic.

Similar agreements were reached with Carthage Area Hospital and the Mohawk Valley Health System in Utica.

In April 2022, Lewis County Health System broke ground on a new two-story surgical pavilion. The project will also include the renovation of medical, surgical and ICU units at the hospital.
