The Hanzōmon Line (半蔵門線, Hanzōmon-sen) is a subway line in Tokyo, Japan, owned and operated by Tokyo Metro.

The line is named after the west gate of the Tokyo Imperial Palace, Hanzōmon (半蔵門), which in turn is named after 16th century samurai Hattori Hanzō, who was important to the founding of the shogunate which built the palace. The Hanzōmon Line's color on maps and station guides is purple, and stations carry the letter "Z" followed by a two-digit number.
