PURPOSE: A reinforcement structure of a multistage streetlight post is provided to prevent a post from being deformed or damaged due to an external force by reinforcing the joint force and support force of a joint between the upper and lower posts. CONSTITUTION: A reinforcement structure of a multistage streetlight post comprises a supporting pipe body(300) and a holding pipe body(400). The supporting pipe body is hollow in order to respond to the lower external diameter of an upper post(100) and is fixed in the upper part of a lower post(200). The holding pipe body fixedly holds the lower surface of the supporting pipe body. The lower side of the upper post is inserted into a gap between the inner circumference of the supporting pipe body and the outer circumference of the holding pipe body. The upper and lower posts are formed with flanges(110,210) for bolting.
