A vehicle circumference monitoring apparatus includes: an acquisition section that acquires a steering angle of front wheels of a vehicle; a trajectory calculation section that calculates a rear wheel width trajectory indicating a moving predicted path of a rear wheel of an inside of turning during turning of the vehicle by steering of the front wheels; and a display control section that superimpose-displays the rear wheel width trajectory in captured side image data output from an imaging section that captures side images of the vehicle when the steering angle of the vehicle is equal to or greater than a predetermined value.
