The Musashino Line (武蔵野線 Musashino-sen?) is a railway line operated by the East Japan Railway Company (JR East). It links Tsurumi Station in Yokohama with Nishi-Funabashi Station in Chiba Prefecture, forming a 100.6 km unclosed loop around central Tokyo. Passenger operations are limited to the 71.8 km portion between Fuchū-Hommachi and Nishi-Funabashi; the Tsurumi to Fuchū-Hommachi portion, called the Musashino South Line, is normally used only by freight trains.
Other services include:
- Musashino: services operated between Fuchū-Hommachi/Hachiōji and Ōmiya
- Shimōsa: services operated between Ōmiya and Nishi-Funabashi
- Holiday Kaisoku Kamakura seasonal service between Minami-Koshigaya and Kamakura
- Burari Kamakura and Yokohama Bay Area seasonal service between Iwaki and Kamakura
- Burari Takao Sansaku seasonal service between Hitachi and Takao
Tsurumi Station is considered to be the origin of the Musashino Line; trains going clockwise (toward Nishi-Funabashi) are therefore referred to as heading "down" (下り kudari?), while trains going counter-clockwise (toward Fuchū-Hommachi) are heading "up" (上り nobori?). This is often counterintuitive, as it results in through trains to Tokyo being labeled and numbered as "down" trains while on the Musashino Line; however, such trains switch to "up" after joining the Keiyō Line.
All passenger trains begin service at Fuchū-Hommachi Station; details on the Musashino South Line freight-only section can be found below the passenger station list.

165 and 169 series EMUs were used on Shinkansen Relay services and later Musashino rapid services until 2002. 115 series EMUs were used on Musashino services from 2002 until the services were downgraded to all-stations "Local" status in December 2010.
The Musashino Line was initially envisioned as a "Tokyo Outer Loop Line" in a 1927 railway appropriations bill, but was not built for several decades due to World War II and its aftermath. Construction finally began in 1964.
In 1967, a train carrying jet fuel to Tachikawa Air Base in western Tokyo exploded while passing through Shinjuku Station. This disaster led to the banning of freight trains on railway lines in central Tokyo and sped the development of the Musashino Line as an alternative route. Because most of the line passed through sparsely populated areas, it was initially envisioned as a freight-only line: however, opposition from local residents, at the same time as the violent landowner battles plaguing Narita International Airport, led the railway authorities to agree to passenger service as well.
The northern portion of the line (Fuchū to Funabashi) was completed in 1973; the southern freight-only portion (Fuchū to Tsurumi) was completed in 1976. The line remains in use for transporting US military jet fuel from Yokohama to west Tokyo, among other purposes.

- Aichi Loop Line, counterpart around Nagoya
