Line 3 (simplified Chinese: 三号线; traditional Chinese: 三號線; pinyin: Sānhào Xiàn; Jyutping: Saam1 Hou6 Sin3) of the Shenzhen Metro (Longgang Line)(龙岗线; 龍崗線; Lónggǎng Xiàn; Lung4 Gong1 Sin3) runs northeastward from Yitian to Shuanglong. Line 3 opened on December 28, 2010. It also has an unofficial name Universiade Line because it connected the Universiade playground and the center of Shenzhen.

Since opening, it has been heavily trafficked highly and became a major transport option for urban workers. Approximately 433,400 use Line 3 every day in 2013. On January 1, 2017 Line 3 carried a peak ridership of 919,000 people.

It currently has a service interval of 5 minutes between trains across the entire length of the line. Sectional trains operate on weekdays, between Huaxin and Tangkeng, from 7:15 a.m. to 9:15 a.m. and from 5:45 p.m. to 7:45 p.m. This is to alleviate a surge in passenger traffic at Buji Station, since the opening of the connecting Shenzhen East Railway Station.

The first phase of Shenzhen Metro Line 3 started construction in July 2007. On April 23, 2008, the Shenzhen Municipal Planning Bureau renamed the still under construction Shenzhen Metro Line 3 to "Longgang Line". The renaming was later reverted in 2013. The first phase of the line from Shuanglong to Caopu stations officially began operations on December 28, 2010. This section is almost entirely elevated except near Tangkeng Station It starts from Longgang District and runs mainly along Shenhui Road, to Luohu District. The first phase has 16 stations, with a total length of 25.138 km. The second phase of the line from Hongling to Yitian stations, opened on June 28, 2011.
