A laser processing apparatus includes a table that places a work thereon, a processing head that emits a laser beam toward the work, a head unit that supports the processing head, a first mover that moves the head unit along the table along a first axis, a second mover that moves the head unit along the table along a second axis, a rotor supported in the head unit and turnable around a third axis orthogonal to the first and second axes, and a linear mover supported inside the rotor and linearly movable in both directions along a diameter of the rotor for a predetermined movable distance shorter than the diameter of the rotor, the linear mover supporting the processing head so that the laser beam from the processing head advances along a fourth axis parallel to the third axis.
