An endoscope system includes a first endoscope that includes a first observation optical system with a first viewing angle and a second endoscope that includes a second observation optical system with a second viewing angle wider than the first viewing angle. A second distance from a second distal end face of an insertion portion of the second endoscope to a minimum focal point of the second observation optical system is shorter than a first distance from a first distal end face of a distal end portion of the first endoscope to a minimum focal point of the first observation optical system.
