The Ryōmō Line (両毛線 Ryōmō-sen?) is a Japanese railway line connecting Oyama in Tochigi Prefecture with Maebashi in Gunma Prefecture. 84.4 km (52.4 mi) long, the line is owned and operated by the East Japan Railway Company (JR East). The name refers to the fact that Gunma and Tochigi prefectures were once part of an ancient province called Keno (毛野?), which was later split into Kōzuke (Gunma) and Shimotsuke (Tochigi). This line connects both halves of the old province.
Most Ryōmō Line services continue beyond Shin-Maebashi and terminate at Takasaki on the Jōetsu Line. Local trains run about once in an hour during the day between Oyama and Maebashi and twice or three times as frequently between Maebashi and Takasaki. Some rapid services from Ueno and the Shōnan-Shinjuku Line travel through onto the Ryōmō Line, but they stop at every station.
Akagi limited express services travel to Maebashi from Ueno (four times daily to Maebashi, two or three times daily to Ueno) or Shinjuku (one round trip daily). On the weekdays some Akagi services are branded Swallow Akagi.

The Oyama to Kiryu section was opened in 1888 by the Ryomo Railway, and extended to Shin-Maebashi the following year. The company merged with the Nippon Railway in 1897, and that company was nationalised in 1906.
The line was electrified in 1968, the same year the Iwafune - Sano and Komagata - Maebashi sections were double-tracked.
Freight services ceased in 2004.
