The Shinonoi Line (篠ノ井線 Shinonoi-sen?) is a railway line in Nagano Prefecture, Japan, operated by the East Japan Railway Company (JR East). It connects Shinonoi Station in Nagano to Shiojiri Station in Shiojiri.
The line is a corridor between the Shinetsu Main Line and the Chūō Main Line. All the limited express trains on the Shinonoi Line come from the Chūō Main Line: Azusa and Super Azusa from Tokyo and Shinano from Nagoya.
The Shinonoi to Nishijo section opened in 1900, and was extended through Matsumoto to Shiojiri in 1902.
The Shiojiri - Matsumoto section was duplicated between 1961 and 1965, with the Tazawa - Akashina section duplicated in 1966. The Akashina to Nishijo section was also duplicated, but the original line was decommissioned in 1988.
The Shiojiri - Matsumoto section was electrified in 1964/5, and extended to Shinonoi in 1973, CTC signalling being commissioned on the entire line the previous year.
