A polyclinic (or policlinic), is a place where a wide range of health care services (including diagnostics) can be obtained without the need for an overnight stay. Polyclinics are sometimes co-located with a hospital.

Greek polis city, klinike (techne) "(practice) at the sickbed," from klinikos "of the bed," kline "bed, couch, that on which one lies". Literally city-clinic, in fact "a clinic held in a private house".

A typical polyclinic is an outpatient facility that houses general medical practitioners (GPs) such as doctors and nurses to provide ambulatory care and some acute care services but lacks the major surgical and pre- and post-operative care facilities commonly associated with hospitals. Besides GPs a polyclinic can house outpatient departments of some medical specialties i.e. gynecology, dermatology, ophthalmology, ENT, neurology, pulmonology, cardiology, endocrinology etc. In some university cities polyclinics house outpatient departments of all the teaching hospital in one building.
