The Toei Shinjuku Line (都営新宿線, Toei Shinjuku-sen) is a rapid transit line in Tokyo and Chiba Prefecture, Japan, operated by the municipal Toei Subway. The line runs between Motoyawata in Ichikawa, Chiba in the east and Shinjuku in the west. At Shinjuku, most trains continue as through services to Sasazuka on the Keiō New Line, with some services continuing to Hashimoto in Sagamihara, Kanagawa via the Keiō Line and the Keiō Sagamihara Line.

On maps and signboards, the line is shown in the color leaf green. Stations carry the letter "S" followed by a two-digit number inside a lime green circle.

In fiscal year 2023, the Shinjuku Line was Toei's third most profitable line, earning ¥6.25 billion in surplus. It served 704,235 passengers on average per day, the second highest in the Toei network (after the Oedo Line).

The name “Shinjuku Line” dates to 1903, when a Tokyo tram line of the same name opened, operating above ground between Shinjuku and Yotsuya, along the same route of the present-day Tokyo Metro Marunouchi Line. The name predates the Seibu Shinjuku Line, which was renamed from the Murayama Line in 1952.
