TheNagareyama Line (流山線,Nagareyama-sen) is acommuter rail line inChiba Prefecture, Japan, operated byRyutetsu (流鉄株式会社,Ryūtetsu kabushiki-kaisha) betweenMabashi Station inMatsudo andNagareyama Station inNagareyama. The line and the operator company was called the Sōbu Nagareyama Line (総武流山線,Sōbu Nagareyama-sen) and Sōbu Nagareyama Electric Railway (総武流山電鉄,Sōbu Nagareyama Dentetsu) respectively until the renaming on August 1, 2008.^[1] The present line name was the most popular short name of the line. It was also called Ryūden (流電).

This is the only line Ryūtetsu operates, making the company unique for being an independent railway operator with just a single 5.7 km line and no major subsidiary businesses (unlikeYamaman, orThe Oriental Land Company and theirDisney Resort Line). The short line functions as a link between the centre of the city of Nagareyama and theEast Japan Railway Company (JR East)Jōban Line. However, after the opening of theTsukuba Express on August 24, 2005, ridership fell sharply.Suica andPASMOcontactless smart cards cannot be used, and Ryūtetsu reportedly has no plans to introduce the system on the line.

The company was incorporated on November 7, 1913 as Nagareyama Light Railway (流山軽便鉄道,Nagareyama Keiben Tetsudō) and opened a762 mm (2 ft 6 in) gauge railway on March 14, 1916. The company renamed Nagareyama Railway (流山鉄道,Nagareyama Tetsudō) in November 1922 and rebuilt the railway track to1,067 mm (3 ft 6 in) gauge in 1924.^[1]

The company name was again changed to Nagareyama Electric Railway (Nagareyama Denki Tetsudō) in 1949, to Nagareyama Electric Railway (Nagareyama Dentetsu) in 1967, to Sōbu Nagareyama Electric Railway in 1971 and to Ryūtetsu in 2008.^[1]
