Shek Mun (Chinese: 石門) is a station on the Tuen Ma line of Hong Kong. To the west, it serves the Shek Mun Industrial Area and northeastern portion of City One, including Siu Lek Yuen Playground. A new campus of the Hong Kong Baptist University (including a primary and a secondary school) is situated just outside exit D, to the east of the station.

On 21 December 2004, Shek Mun station opened to the public with other KCR Ma On Shan Rail stations.

On 14 February 2020, the Ma On Shan line was extended south to a new terminus in Kai Tak, as part of the first phase of the Shatin to Central Link Project. The Ma On Shan Line was renamed Tuen Ma Line Phase 1 at the time. Shek Mun station became an intermediate station on this temporary new line.

On 27 June 2021, the Tuen Ma line Phase 1 officially merged with the West Rail line in East Kowloon to form the new Tuen Ma line, as part of the Shatin to Central link project. Hence, Shek Mun was included in the project and is now an intermediate station on the Tuen Ma line, Hong Kong's longest railway line.
