Longtan station () is an interchange station between Line 11 and Line 18 of the Guangzhou Metro, located underground between Xinjiao Middle Road and Taichong in Guangzhou's Haizhu District. It opened on 28 September 2021. Line 11 started operations at this station on 28 December 2024.
The rails for Line 11 at this station connects to the nearby Chisha Depot. Thus, this is the terminating station for Outer Circle Line 11 trains returning to the depot.
The station has 7 points of entry/exit. Exits B, C and D opened with the station's initial opening. When Line 11 opened, Exits A, E, F and G opened. Exits B, F and G are accessible via elevators.
During the EIA announcement of Line 11, the proximity of the station to the Haizhu Wetland Park and the fact that two entrances and exits entered the planned land area of the wetland park caused concern among citizens and environmental groups. In order to protect the environment of the wetland park, Line 11 cancelled the subway entrance on the sidewalk at the entrance of the wetland park in the follow-up plan.
During planning, the station was called Shiliugang station. In June 2020, the Guangzhou Civil Affairs Bureau announced that the station was initially named Haizhu Wetland station. In February 2021, the station name was finally decided to be Longtan station.
On 28 September 2021, the Line 18 station opened.
During COVID-19 pandemic control rules at the end of 2022, due to the impact of prevention and control measures, station service was suspended from 20:00 on 30 October 2022 to the afternoon of 30 November 2022.
On 30 July 2024, the Line 11 station completed the "three rights" transfer. On 28 December, the station was opened with the opening of Line 11, and the station became an interchange station.
