The invention discloses a gear angle offset measuring device and method based on a laser displacement sensor in the technical field of gear measurement, and the device comprises a workbench which is provided with a workpiece rotating platform and a two-coordinate translation mechanism which comprises an X-axis guide rail fixed at the upper side of the workbench. A central positioning mandrel is vertically arranged on the workpiece rotary table, a Y-axis guide rail is slidably connected to the X-axis guide rail, a lifting frame is slidably connected to the Y-axis guide rail, a laser displacement sensor is connected to the lifting frame, the central plane of the X-axis guide rail passes through the center of the workpiece rotary table, and a base of the laser displacement sensor is an angle-adjustable index plate. Through the index plate, the position of the laser beam relative to the center of the gear is changed for offset measurement. The method can achieve the measurement of a complex gear, and is good in p
