A clinic (or outpatient clinic or ambulatory care clinic) is a healthcare facility that is primarily focused on the care of outpatients. Clinics can be privately operated or publicly managed and funded. They typically cover the primary healthcare needs of populations in local communities, in contrast to larger hospitals which offer specialised treatments and admit inpatients for overnight stays.

Most commonly, the English word clinic refers to a general medical practice, run by one or more general practitioners, but it can also mean a specialist clinic. Some clinics retain the name “clinic” even while growing into institutions as large as major hospitals or becoming associated with a hospital or medical school.
