Shinjuku Golden Gai is a small area, which is located in Kabukicho, Shinjuku, Tokyo, Japan. It is composed of a network of six narrow alleys, connected by even narrower passageways which are about wide enough for a single person to pass through. Over 200 tiny shanty-style bars, clubs and eateries are squeezed into this area.

The alleys are private roads, not public roads. In this area, shooting photographs and video for all purposes on the street is prohibited without permission of the area's business promotion association.

Golden Gai is a few minutes' walk from the East Exit of Shinjuku Station, between the Shinjuku City Office and the Hanazono Shrine. Its architectural importance is that it provides a view into the relatively recent past of Tokyo, when large parts of the city resembled present-day Golden Gai, particularly in terms of the extremely narrow lanes and the tiny two-story buildings.
