A parking support apparatus includes: a host vehicle positional information acquisition unit acquiring host vehicle positional information indicating a current position of a vehicle; an obliqueness calculation unit calculating obliqueness between a vehicle length direction and a longitudinal direction of the parking space, based on the host vehicle positional information; an obliqueness correction path calculation unit calculating an obliqueness correction path along which a position of the vehicle reaches a front end of the parking space, based on the obliqueness when the vehicle travels forward from a stop position at a steering angle; and a centering path calculation unit calculating a centering path which has a width at a central portion of the parking space in a width direction and along which the vehicle travels forward toward a central region set in the longitudinal direction, after a position of the vehicle reaches the front end of the parking space.
