Tai Shui Hang (Chinese: 大水坑; Cantonese Yale: Daaihséuihāang) is an MTR station on the Tuen Ma line in Hong Kong.

It serves residential estates including Kam Tai Court, Mountain Shore, Chevalier Garden and Sausalito, Tai Shui Hang Village and Sha Tin Fishermen's New Village.

The pattern featured on the platform pillar and glass barrier is a shot of nature representing the Ma On Shan Country Park.

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.

Hence, Tai Shui Hang was included in the project and is now an intermediate station on the Tuen Ma line, Hong Kong's longest railway line.
