The invention discloses an automobile rearview mirror with a blind spot early warning prompt, which is provided with a stepping motor controlling the rearview mirror to rotate, an angle detection device for detecting a rotation angle of the stepping motor, a control unit for calculating the current blind spot of the rearview mirror according to the rotation angle detected by the angle detection device, a directional narrow wave radar arranged below the rearview mirror, wherein the control unit adjusts a radar wave emission angle of the directional narrow wave radar according to the calculated blind spot of the rearview mirror to allow a radar beam angle to cover the blind spot of the rearview mirror during operation; and when the radar monitors a vehicle, the control unit gives an alarm to remind a driver. With the adoption of the technical scheme, the automobile rearview mirror with the blind spot early warning prompt effectively avoids traffic accidents caused by the blind spot by detecting the blind spot of the rearview mirror and judging whether the vehicle exists in the blind spot via the radar; and since the technical scheme adopted by the rearview mirror is mature, the rearview mirror is low in cost and very suitable for large-scale popularization and use.
