The Toei Asakusa Line (都営地下鉄浅草線, Toei Chikatetsu Asakusa-sen) is a subway line in Tokyo, Japan, operated by the municipal subway operator Toei Subway. The line runs between Nishi-magome in Ōta and Oshiage in Sumida. The line is named after the Asakusa district, a cultural center of Tokyo, under which it passes.

The Asakusa Line was the first subway line in Japan to offer through services with a private railway. Today, it has more through services to other lines than any other subway line in Tokyo. Keikyu operates through trains on the Keikyu Main Line to Misakiguchi and the Keikyu Airport Line to Haneda Airport Domestic Terminal. The Keisei Electric Railway operates through trains on the Keisei Oshiage Line to Inba-Nihon-Idai and the Keisei Main Line to Narita Airport Terminal 1, and the Shibayama Railway runs trains via the Keisei Main Line and the Shibayama Railway Line to Shibayama-Chiyoda. Via its through services with Keisei and Keikyu, the Asakusa line is the only train line that offers a direct connection between Tokyo's two main airports.

The Asakusa Line is often split into two routes: Oshiage–Sengakuji and Sengakuji–Nishi-magome; only some trains make all station stops on the line, as many trains travel on the Keikyu Main Line south of Sengakuji.

On maps and signboards, the line is shown in the color rose. Stations carry the letter "A" followed by a two-digit number inside a more reddish vermilion circle.
