This automatic travel system is provided with: a satellite positioning module (31) that calculates positioning data on the basis of satellite signals; a first body position calculation unit (55) that calculates a first body position on the basis of the positioning data; a second body position calculation unit (50) that calculates a second body position by processing a distance measurement signal from the distance measurement sensor (32) using an SLAM algorithm; and an automatic travel control unit (60). The automatic travel control unit (60) has a first mode in which automatic travel control is performed on the basis of the first body position and a second mode in which automatic travel control is performed on the basis of the second body position, and when the traveling body moves from a second region in which the calculation of the positioning data cannot be performed to a first region in which the calculation of the positioning data can be performed. A second mode is set in the second region, and a first m
