PURPOSE: A coupling structure of a street light post is provided to facilitate the maintenance through partial replacement and prevent the infiltration of water into the lower post. CONSTITUTION: A coupling structure of a street light post comprises a lower post(10), a support member(30), an upper post(50), a fastening member, and a cap(90). The support member comprises a support pipe, an upper reinforcement ring which is fixed to the upper periphery of the support pipe and has a coupling hole, and a lower reinforcement ring which is attached to the lower periphery of the support pipe. The support member is attached to the upper part of the lower post in which the lower reinforcement ring and the support pipe are inserted. A fixing ring having a through hole corresponding to the coupling hole of the upper reinforcement ring is fixed to the upper periphery of the upper post. The upper post is inserted in the support pipe. The fastening member is coupled to the coupling hole of the upper reinforcement ring by passing through the through hole of the fixing ring, thereby fixing the fixing ring to the upper reinforcement ring. The cap has a through hole(910) which the upper post passes through and is arranged to accommodate the fixing ring.
