Line 9 of the Beijing Subway (Chinese: 北京地铁9号线; pinyin: běijīng dìtiě jiǔhào xiàn) is rapid transit line in western Beijing. The line runs 16.5 km from the National Library to Guogongzhuang in Fengtai District with nine stations. The line has 13 stations. Line 9's color is      chartreuse.

In 1989, the State Council decided to build Beijing West Railway Station on the Beijing-Kowloon Railway. Subway planning had determined that Beijing West Railway Station shall be the interchange between Lines 7 and 9. However, no provision for an interchange station was added in the railway station's design. The railway station was completed in 1996. 15 years later Beijing West Station was rebuilt and expanded with provisions were added to the basement of the station for Lines 7 and 9. In 2002, in preparation for the 2008 Beijing Olympics, it was proposed that the first section of Line 9 should be built between Baishiqiao to Beijing West Railway Station (today's National Library to Beijing West Railway Station section). The entire length of the proposed line was 5.8 kilometers. However the line only started construction in April 2007, with a planned opening date of 2010 and the original northern section between Baishiqiao to Beijing West Station was further delayed until 2012, making an opening before the Olympics unlikely.

In December 31, 2011 the 11.1 km, 9 station southern section from Guogongzhuang to Beijing West Railway Station opened. At the time the line was only connected to the Fangshan Line, isolated from the rest of the Beijing Subway network. Passengers had to transfer to shuttle buses that connected to the main subway network to continue their journey. That is why in 2011, the line was sparsely used. The situation did not improve in April 29, 2012 when the Beijing subway exceeded a record 8 million daily riders, with the daily ridership of Line 9 being only 46,300.
