Line 14 of the Guangzhou Metro is a rapid transit line in Guangzhou. Like Line 21, Line 14 is a rapid suburban metro line envisioned to promote development in Guangzhou's northeast regions. To facilitate rapid movement between the city center and the outlying district of Conghua within one hour, unlike other pre-existing Guangzhou Metro lines, Line 14 contains passing loops at some stations to allow for express stopping patterns. The trains in Line 14 reach a maximum service speed of 120 km/h (75 mph). These considerations will allow for passengers to travel from outer Guangzhou to the city center in one hour. Line 14 features two separate services. The mainline which opened on December 28, 2018, connects Jiahewanggang in Baiyun to Dongfeng in Conghua. The Knowledge City Line, originally a branch line, is now a standalone service. Passengers can use a cross-platform interchange between the Line 14 mainline and Knowledge City line at Xinhe station. The Knowledge City Line runs from Xinhe in Baiyun to Zhenlong in Huangpu.

The Guangzhou Metro is the rapid transit system of the city of Guangzhou in the Guangdong Province of China. It is operated by the state-owned Guangzhou Metro Corporation and was the fourth metro system to be built in mainland China, after those of Beijing, Tianjin, and Shanghai.
