A laser indicator for golf enables a golfer to maintain a correct posture when he or she enjoys putting or driving a golf ball. The laser indicator includes a case having a window on a front surface, a clamp fixedly secured to the case so as to detachably attach the case to a cap worn by a golfer, a laser module disposed within the case to irradiate a point laser beam and having an optical path in alignment with the window of the case, a switch mounted on the case for allowing the golfer to control electricity supply to the laser module, and a laser beam converter provided between the window of the case and the laser module for movement into alignment with the optical path of the laser module and adapted to convert the point laser beam to a line laser beam.
