The Tokyo Metro Namboku Line (東京メトロ南北線, Tōkyō Metoro Nanboku-sen, South-North Line) is a subway line owned and operated by Tokyo Metro in Tokyo, Japan. The line runs between Meguro in Shinagawa and Akabane-Iwabuchi in Kita. The Namboku Line was referred to as Line 7 during the planning stages, thus the seldom-used official name is Line 7 Namboku Line (7号線南北線, Nana-gō-sen Nanboku-sen).
On maps, diagrams and signboards, the line is shown using the color emerald (previously coded "teal"), and its stations are given numbers using the letter "N".
