A laser processing method for cutting, by laser beam, a cutting path (A 0 ) of a workpiece having a corner (B) between a first cutting path (A 1 ) and a second cutting path (A 2 ) is provided. The workpiece is cut under the first cutting conditions (X) from the first cutting path to the corner, and under the second cutting conditions smaller in cutting ability than the first cutting conditions for a predetermined section (A 21 ) on the second cutting path from the corner. The workpiece is cut under the first cutting conditions on the second cutting path after finished the predetermined section. The cutting conditions are continuously changed at the time of switching from the first cutting conditions to the second cutting conditions and/or from the second cutting conditions to the first cutting conditions. In this way, a processing defect is prevented while suppressing the delay of the cutting time at the time of cutting along the cutting path including the corner.
