A hitch angle detection system to detect a trailer hitch angle with a simple, versatile configuration is provided. Edge detection is performed in a portion including an image of a rear bumper of a tractor and an image of a front bumper of a trailer, the portion being included in an image captured by a rear camera, to extract an edge of the tractor rear bumper image and an edge of the trailer front bumper image. A straight line with which the edge of the rear bumper image is best approximated is calculated as a straight line parallel with the tractor left-right direction. A straight line with which the edge of the trailer front bumper image is best approximated is calculated as a straight line parallel with the trailer left-right direction. The relative angle of the straight line to the straight line is calculated as the trailer hitch angle.
