A parking assist system includes: a control device configured to control a vehicle so as to move the vehicle autonomously from a current position to a target position; and an external environment sensor configured to detect an obstacle. During control of the vehicle to the target position, the control device is configured to recognize the obstacle present in a first area and a second area based on information from the external environment sensor. In a case where the control device recognizes the obstacle in the first area, the control device stops the vehicle, and in a case where the control device recognizes the obstacle in the second area and the obstacle in the second area is a moving object and/or a moving creature, the control device moves the vehicle in a decelerated state in which the vehicle is decelerated to a prescribed speed.
