A laser surveying apparatus includes: a laser light source configured to emit a laser light flux; a laser projector supported tiltably and configured to rotatably irradiate the laser light flux emitted from the laser light source; a mechanism tiltably supporting the laser projector; tilting arms extending in an X-direction and a Y-direction substantially perpendicular to the laser projector; a tilt driving section provided to at least one of the tilting arms configured to drive corresponding at least one of the tilting arms; detectors provided to each of the tilting arms and each configured to detect a movement amount of the corresponding one of the tilting arms, and an arithmetic section configured to calculate an inclination of the laser projector in the X-direction and the Y-direction from each of the movement amounts of the tilting arms detected by the corresponding detectors.
