The Uetsu Main Line (羽越本線 Uetsu-hon-sen?) is a railway line in the Tōhoku and Chūbu regions of Japan. Part of the East Japan Railway Company (JR East) system, it connects Niitsu Station in the city of Niigata and Akita Station in Akita. The name "Uetsu" refers to the ancient provinces of Dewa (出羽) and Echigo (越後), which the line connects.
The line was opened in sections between 1912 and 1924, and electrified in 1972, the same year CTC signalling was commissioned.
Work to duplicate the line in sections commenced in 1957, and continued for 25 years until being suspended due to capital expenditure restrictions in 1983, at which time 51% of the route was duplicated, although the longest continuous duplicated section is 27.3km. In many sections the track is located on a narrow shelf between the ocean and adjacent mountains, meaning duplication often required constructing long tunnels on the inland side of the original line to accommodate the second track. The completed work includes 11 tunnels each over 1km long (the longest being 2.3km), and the suspension of works resulted in the completed tunnel between Koiwagawa and Atsumi Onsen stations remaining unused.
Former connecting lines
- Shibata station - Plans by the Ministry of Commerce to mine an iron ore deposit in 1918 resulted in the construction of a line to service the mine. 14km had been built when construction was abandoned in 1920 following the collapse in the iron ore price. In 1925 the line was transferred to the Ministry of Railways and opened as a development line, called the Akatani Line. In 1941 the line was extended 5km to Higashiakatani to connect to the Nittetsu Mining Co railway, which operated a 4km line serving an iron ore mine until 1956. The Akatani line closed in 1984.
- Tsuruoka station - The Shonai Electric Railway Co. operated a 12km line to Yunohama Onsen, electrified at 600 VDC, from 1929 until 1975.

On December 25, 2005, all six cars of a limited express train Inaho No.14 on the Uetsu Line derailed in Yamagata prefecture, about 350 kilometres (220 mi) north of Tokyo. The train was headed south towards Kita-Amarume Station. Three of the cars turned over, causing the deaths of five people and injuring 33 others. Three other persons were originally reported missing, but authorities later discovered that they had disembarked from the train before the accident.
