Tin Shui Wai (Chinese: 天水圍; Cantonese Yale: Tīnséuiwài) is an MTR station on the Tuen Ma line, located in Ping Shan near Tin Shui Wai New Town, Yuen Long District.

It is the only heavy rail station serving Tin Shui Wai, which has a population of around 300,000.

Tin Shui Wai was included in the project and is now an intermediate station on the Tuen Ma line.

Three footbridges are constructed along Tin Fuk Road and Ping Ha Road to connect the station to the highly populated urban area that the station is built in.

A public transport interchange is located to the southwest of the station.
