An object of the invention is to provide an endoscope system capable of keep ready track of the position of a subject of interest by indicating the direction of the subject of interest, even when there is no display of the subject of the interest. The endoscope system 10 includes an endoscope 1 including an imaging unit 1a that is capable of taking an image of a subject of interest Pt, a display unit 6 for displaying an image taken by the imaging unit 1a, an endoscopic position sensor 5 for detecting a position of the endoscope 1 in the body cavity B, a distance measurement unit 1c for measuring a distance from a distal end of the endoscope 1 to the subject of interest Pt, a position calculation unit 71 for computing the positions of the distal end of the endoscope 1 and the subject of interest Pt on the basis of information from the endoscopic position sensor 5 and the distance measurement unit 1c, a position storage unit 72 for storing a position of the subject of interest Pt computed by the position calculation unit 71, and a direction indication unit 75 for indicating a direction in which the subject of interest is present on the display unit 6.
