Hanzōmon Station (半蔵門駅) is a subway station on the Tokyo Metro Hanzōmon Line in Chiyoda, Tokyo, Japan, operated by the Tokyo subway operator Tokyo Metro. It is located near the Hanzōmon Gate of the Imperial Palace.

The station was the eastern terminal of the Hanzōmon Line from 1982 to 1989 and is still used as a terminal for some morning rush hour trains. It is the only station on the Hanzōmon Line not to connect with any other subway or railway lines; however, it is a five-minute walk from Kōjimachi Station on the Tokyo Metro Yurakucho Line.

The station is composed of a singular island platform serving two tracks.

History
Hanzōmon Station opened on 9 December 1982, as the eastern terminus of the Hanzōmon Line at the time. It became a through station when the Hanzōmon Line was extended to Mitsukoshimae.

The station facilities were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.
