A parking support apparatus sets a plurality of candidate connection positions along a reverse direction route, calculates a first connection route, calculates a first parking route by using the first connection route and the reverse direction route, judges whether the candidate connection position exists within a recognition range or not; and if the candidate connection position does not exist within the recognition range, calculates a shortest steering wheel turning position, calculates a second connection route capable of reaching any one of the candidate connection positions calculates a second parking route by using the second connection route and the reverse direction route, when the second parking route can be calculated, the second parking route is selected as the parking route; otherwise, the first parking route is selected as the parking route.
