The Seibu Tamako Line (西武多摩湖線, Seibu Tamako-sen) is a 9.2-kilometre (5.7 mi) single-track railway line in Tokyo, Japan, operated by the private railway operator Seibu Railway.

The line is part of the Seibu Shinjuku group of railway lines that connects suburban areas of western Tokyo to Seibu and JR East main lines that extend to central Tokyo. The line is named after the Tama Lake (多摩湖, Tamako), a major reservoir supplying water to Tokyo, located close to the terminus of the line at Tamako. Since July 2008, recorded announcements on trains have been provided in English in addition to Japanese and, as part of Seibu Railway's ongoing refurbishment programme, signage and maps at stations are also bilingual.

All services on this line operate as all-stations "Local" (普通列車, futsū-ressha) services, mainly for the full length of the line between Tamako and Kokubunji stations, with other services terminating at starting from the middle station, Hagiyama.^[1] The line is single track except at Hitotsubashi-Gakuen station and Hagiyama station, where services in operation routinely pass each other.

This line connects the suburban Seibu lines with the JR Chūō line at Kokubunji. At Hagiyama, there is transfer to the Seibu Haijima Line. The Seibu Yamaguchi Line, also known as the Leo Liner, connects Tamako Station with Seibuen Amusement park and the Seibu Dome, home of the Saitama Seibu Lions baseball team. Ōmekaidō Station is listed as a connection to services on the JR Musashino Line at Shin-Kodaira Station, a short walk away.

The Tamako Line also provides access to the National Center of Neurology and Psychiatry^[2] and the International Campus of Hitotsubashi Gakuen University^[3] from Hagiyama and Hitotsubashi-Gakuen stations respectively.

The Tamako Railway opened the Kokubunji to Hagiyama section in 1928, and extended it to Musashi-Yamato in 1930, electrifying the entire section at 600 V DC at the same time.^{[citation needed]} The company was absorbed into the Seibu Railway system on 12 March 1940.^[4]　In 1961, the line was extended to Seibu-yūenchi (now Tamako), and the voltage increased to 1,500 V DC at the same time.^{[citation needed]}
