Tin Shui Wai Connection (Chinese: 天水連線) is a local political group based in Tin Shui Wai founded in 2019 by a group of LIHKG netizens. In a historic pro-democracy landslide in 2019 District Council election, the group won four seats in the Yuen Long District Council.

Tin Shui Wai Connection was formed by a group of five LIHKG netizens in their 20s who attempted to prevent pro-Beijing candidates from winning uncontestedly in the Yuen Long District Council constituencies in Tin Shui Wai in the 2019 District Council election, which were Hau Man-kin who intended to run in Tin Shing, Leung Chin-hang in Tin Yiu, Lam Chun in Shui Wah, Ng Kin-wai in Kingswood North and Kwan Chun-sang in Fu Yan.^[1]

Ex-member Leung Chin-hang who had run in the same constituency in the 2015 election faced another pro-democrat candidate, Ho Wai-pan of the Neighbourhood and Worker's Service Centre (NWSC). Two candidates ran in a primary ahead the election, but the result was seen invalid as it did not meet the 800-vote threshold. Leung quit the TSW Connection afterward and ran as an independent.^[2]

The rest of the candidates all won the election, gaining four seats in total and became the second largest political grouping in the Yuen Long District Council.
