The present invention is directed to provide an endoscope system capable of preventing an actuation which an operator does not intend on the basis of a placement state of an endoscope. An endoscope system includes at least an endoscope 20 of the endoscope 20 and an accessory 44, a placement means on which the endoscope 20 is placed, a detecting means 72 configured to detect whether the endoscope 20 is placed on the placement means or not, an actuating means 58 for at least one of the endoscope 20 and the accessory 44, an operating means 62 for operating the actuating means 58, and a control means 60 configured to be switched between a normal mode wherein the actuating means 58 is controlled according to an operation to the operating means 62 and a restricting mode wherein the actuating means 58 is controlled regardless of an operation to the operating means 62, on the basis of a result of detection by the detecting means 72.
