The {{nihongo|Nagareyama Line|流山線|Nagareyama-sen}} is a commuter rail line in Chiba Prefecture, Japan, operated by {{nihongo|Ryutetsu|流鉄株式会社|Ryūtetsu kabushiki-kaisha}} between Mabashi Station in Matsudo and Nagareyama Station in Nagareyama. The line and the operator company was called the {{nihongo|Sōbu Nagareyama Line|総武流山線|Sōbu Nagareyama-sen}} and {{nihongo|Sōbu Nagareyama Electric Railway|総武流山電鉄|Sōbu Nagareyama Dentetsu}} respectively until the renaming on August 1, 2008.{{cite web|url=http://rail.hobidas.com/news/info/article/86164.html|script-title=ja:総武流山電鉄 社名と線名を変更|date=2008-06-27|access-date=2008-10-16|language=ja}} The present line name was the most popular short name of the line. It was also called {{nihongo|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 (unlike Yamaman or The Oriental Land Company and their Disney Resort Line). The short line functions as a link between the centre of the city of Nagareyama and the East Japan Railway Company (JR East) Jōban Line. However, after the opening of the Tsukuba Express on August 24, 2005, ridership fell sharply. Suica and PASMO contactless smart cards cannot be used, and Ryūtetsu reportedly has no plans to introduce the system on the line.
