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

The line is part of the Seibu Shinjuku group of railway lines that connects suburban areas of western Tokyo to Seibu andJR East main lines that extend to central Tokyo. The line is named after theTama Lake (多摩湖,Tamako), a major reservoir supplying water to Tokyo, located close to the terminus of the line atTamako. 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 betweenTamako andKokubunji stations, with other services terminating at starting from the middle station,Hagiyama.^[1]The line is single track except atHitotsubashi-Gakuen station and Hagiyama station, where services in operation routinely pass each other.

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

The Tamako Line also provides access to theNational Center of Neurology and Psychiatry^[2] and the International Campus ofHitotsubashi 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]}

9000 series trainsets were deployed on the Tamako Line from 1 October 2020.^[5]
