A backset adjustable deadbolt for mounting in a lock cylinder is provided. A deadbolt assembly includes an actuator connected to and movable by the movement of the lock cylinder through the lock cylinder connector. A link bar connects the actuator to the deadbolt at a plurality of attachment points. The deadbolt, lock cylinder connector, actuator, link bar form the deadbolt assembly and are mounted in a housing. A releasable connector extends through the housing. In the engaged position, a releasable connector contacts the actuator to lock the actuator remote end in one of the plurality of attachment points in the link bar. In the disengaged position, the releasable connector releases the actuator remote end from the link bar to allow the link bar move relative to the actuator from one of the plurality of attachment points to a different point for reengagement with the actuator remote end.
