A vehicle rear-seat position adjustment apparatus comprising:

• a pair of fixed rails mounted on a floor panel in such a manner as to be spaced apart from each other in a leftward-rightward direction;
• a movable rail fastened to the fixation rail in a manner that is movable backward and forward;
• a leg frame having a structure in which a slot of a predetermined length is formed and fixedly mounted on the fixation rail;
• a tilting link of which a front end portion is connected to the slot in the leg frame in a manner that is movable backward and forward, and is connected by a fourth hinge mechanism to the movable rail;
• a seat cushion frame of which a front end portion is connected by a first hinge mechanism to the leg frame and of which a rear end portion is connected by a second hinge mechanism to a rear end portion of the tilting link;
• a recliner mounted on a side frame in order to recline a seat back of a rear seat;
• and
• a manual operation mechanism connected to the movable rail in a lockable manner and configured to move backward and forward the front end portion of the tilting link fastened by the fourth hinge mechanism to the movable rail.
