Line 13 of the Guangzhou Metro is a rapid transit rail line currently in operation as of 28 December 2017 in Guangzhou, China. It is envisioned to be the "East West express line" complementing Line 3 which is the "North South express line". The line serves some of the most popular areas in Guangzhou such as Luochongwai Bus Terminal, Zhujiang New Town CBD and Yuancun while passing through some of the densest and most populated areas of Tianhe, Yuexiu, and Liwan Districts. Due to the density of the areas served, demand for this line is expected to be high, with an average mature daily ridership predicted at 1.44 million passengers per day when both phases are complete. Knowing this, engineers designed Line 13 to use 8 car wide body Type A rolling stock, the highest capacity rolling stock in the Guangzhou Metro to date. To fulfill its role as a crosstown express service, the line is designed with a service speed of 100 km/h (62 mph) with a wider stop spacing. The first phase runs from Yuzhu in Huangpu to Xinsha in Zengcheng, opened on 28 December 2017 and is expected to initially serve 220,000 riders per day. Phase 2 of the line, from Yuzhu to Chaoyang, is currently under construction and is scheduled to open in stages from 2024/25.

Yuzhu Station, formerly Maogang Station (茅岗站) during planning, is a station on Line 5 and Line 13 of the Guangzhou Metro. It is located under Yumao Road (鱼茅路) near the south of the Maogang Interchange (茅岗立交) on Huangpu Avenue (黄埔大道) in the Huangpu District. It opened in 28 December 2009.
