This cruise control device enables more accurate prediction of running resistance and prevents worsening of fuel economy. In this device, a coasting prediction unit (12c) of an automatic cruise control device (12), which is for performing cruise control of the vehicle (1) on the basis of a resistance coefficient, predicts, on the basis of the resistance coefficient, the change in vehicle speed if the vehicle (1) were to coast; if the vehicle (1) does coast, a vehicle information acquisition unit (12b) acquires information about the detected vehicle speed; and a running resistance updating unit (12f) updates the value of the resistance coefficient on the basis of the information about the change in vehicle speed predicted by the coasting prediction unit (12c) and information about the vehicle speed acquired by the vehicle information acquisition unit (12b).
