Kau Yan Tsung Tsin Church, Protestant church in Sai Ying Pun, Hong Kong.

Kau Yan Tsung Tsin Church stands at the corner of Western Street and High Street in Sai Ying Pun. The Gothic Revival building, completed in 1932, has pointed arches, a steep roof and a tower. It was designed by Palmer & Turner and replaced the earlier Four Corners House on the same site.

The Basel Mission founded the congregation in 1852 as the Hakka Holy Church, moving to this Sai Ying Pun site in 1861, when Rev. Rudolf Lechler built the four-cornered house. The church became self-governing on 25 December 1927 as the Hong Kong Sai Ying Pun Chinese Christian Tsung Tsin Self-Supporting Church. Palmer & Turner designed the present Gothic Revival building, erected from 1 June 1931 and completed on 24 December 1932. It was renamed Kau Yan Church and became fully Cantonese-speaking in 1984.

The congregation uses this building for worship and community gatherings that shape local life in the neighborhood. Visitors often see residents gathering before and after services or participating in local activities throughout the year.

The building sits between Third Street and High Street in an accessible area of the Central and Western District. Visitors should note that the neighborhood is hilly and sturdy footwear is recommended to comfortably reach the entrances.

The 1932 church was built by Palmer & Turner (P&T) on the site of the earlier "Four-Square Building" erected in 1861 by Rev. Rudolf Lechler. The congregation became self-governing on 25 December 1927 as the Hong Kong Sai Ying Pun Chinese Tsung Tsin Self-Supporting Church, and the new chapel was named Kau Yan when it opened on 24 December 1932.
