A tracking control apparatus is configured to include a detection unit that detects an object in front of a host vehicle, and a control unit that, when parallel traveling vehicles which travel in parallel with each other in front of the host vehicle are detected by the detection unit and in a case where a distance between the host vehicle and the parallel traveling vehicles is longer than a separate recognition distance by which a plurality of vehicles in the vehicle-width direction can be separately recognized, presumes that there exists a preceding vehicle between the parallel traveling vehicles and controls traveling of the host vehicle.
