A 3D laser leveler is provided for accurately locating distant parallel or extension lines. The 3D laser leveler has a base block and a rotator. The base block provides a base plane for resting upon a flat surface when in use, a first leveling unit for examining the leveling status of the base plane, and a pivot mechanism. The rotator is rotatably connected to the base block and rotatable around the pivot mechanism, and includes a housing for providing an internal accommodating space, a battery set and a laser unit received inside the accommodating space. The laser unit uses power provided by the battery set for generating a spanning plane laser beam that can be utilized to locate a spatial extension or a perpendicular line. In addition, a joining bracket can be included separately to connect the 3D laser leveler and a conventional beam leveler.
