Line 21 of the Guangzhou Metro (Chinese: 广州地铁21号线; pinyin: Guǎngzhōu Dìtiě Èrshíyīhàoxiàn) is a rapid transit rail line in Guangzhou.

Line 21 is an express suburban metro line along with Line 14. Both lines were envisioned to connect and promote development in the northeast regions of Guangzhou. Line 21's unique role means that it has many design features that make it different from other Guangzhou metro lines. For example, several stations have passing loops to allow for express and local stopping patterns and trains reach a maximum service speed of 120 km/h (75 mph). These considerations allow for passengers to travel from outer Guangzhou to the city center in one hour.^[2] Line 21 runs from Tianhe Park in Tianhe to Zengcheng Square in Zengcheng.^[3] The line is about 60.3 km (37.5 mi) long.^[1] The line has 38.8 km (24.1 mi) of underground sections, 6.8 km (4.2 mi) of mountain base tunneling and 14.7 km (9.1 mi) on viaducts.^[4] The line has a total of 20 stations, of which 16 are underground and 4 are elevated.

The eastern section of Line 21 opened on December 28, 2018^[5] and the western section opened on December 20, 2019.^[6]

Since October 2, 2024, the section from Tianhe Park to Yuancun was removed from Line 21, and once renovation is complete, will transfer to Line 11. Cross Platform transfer will be provided at Tianhe Park station after reopening.^[7]
