Tai Wai Station is an interchange station on the East Rail Line and the Ma On Shan Line of the Mass Transit Railway (MTR) system in Hong Kong. The station is located in Tai Wai, Sha Tin District.

The station was originally opened in 1983 as an intermediate station of East Rail Line. In 2001, the station underwent expansion and construction ended in September 2004. The new concourse part was opened at first in the same month. Since 21 December 2004, the station has served as the terminus of the Ma On Shan Line, as well as the interchange station between these two lines. Passengers from the Ma On Shan Line can change to East Rail Line trains via a station walkway. The cross platform interchange is similar to that found at other MTR stations.

Tai Wai will also become a key station on the MTR's proposed Sha Tin to Central Link.

All platforms are side platforms. Platforms 3 and 4 are positioned slightly higher than Platforms 1 and 2. There are several walkways connecting Platforms 2 and 3 making it possible for passengers to walk directly from the Ma On Shan Line terminus platform onto the East Rail Line southbound platform. There is room for Ma On Shan Line trains to reverse or head for the Maintenance Centre.

Tai Wai (English pronunciation: /ˌtaɪ ˈwaɪ/) is an area in the New Territories of Hong Kong, located between Sha Tin New Town and the Lion Rock. It is the largest part of the Sha Tin District.^{[citation needed]}

With an MTR station serving two lines, 5 bus termini and several tunnels and roads connecting it to other parts of the New Territories, Kowloon and Tsuen Wan, Tai Wai is an important transportation node in Hong Kong.

Sprouting from traditional Chinese farming villages growing rice, Tai Wai area once functioned as a light suburban industrial park in the 1970s. Few factory buildings are still in use, mostly as warehouses. The current urbanization of the area is the consequence of the development of Sha Tin New Town.

Tai Wai village, where the name of the area came from, was the largest and oldest walled village in Sha Tin. It was built in 1574 during the Ming Dynasty, and was called Chik Chuen Wai (Chinese: 積存圍) at the time. It was originally made up of 16 families, Wai (韋), Chan (陳), Ng (吳), Yeung (楊), Wong (黃), Lee (李), Hui (許), Cheng (鄭), Tong (唐), Yuen (袁), Yau (游), Lam (林), Lok (駱), Tam (譚), Mok (莫) and Choy (蔡).
