Cheng Hon Pang Ancestral Hall, Grade III historic ancestral hall in Kam Tin Wai, Yuen Long District, Hong Kong.

Cheng Hon Pang Ancestral Hall stands in Kam Tin Wai, a village of Pat Heung in Yuen Long District, not in Kam Tin. The Cheng clan built it in 1929 after moving from Tsuen Wan's Shing Mun Wai for the Shing Mun Reservoir. A stone cross placed on its roof in 1935, when the hall became Our Lady of Sorrows Chapel, remains visible.

The building was constructed in 1929 and initially served as an ancestral shrine for the family. It was later converted into a Catholic chapel called Our Lady of Sorrows, before returning to its original purpose in the 1960s.

The hall's name honours Cheng Hon Pang of the Cheng clan, whose ancestral tablets were thrown into the Kam Tin River by a priest in 1935. After the hall returned to the clan in 1966, it housed Kam Tsin Wai Kindergarten until 1971. Today villagers use it to discuss village affairs.

The hall stands in Kam Tsin Wai, west of Shui Liu Tin village in Pat Heung, Yuen Long District. It is a village building still used for discussing village affairs, so visits depend on the goodwill of the Cheng clan; there are no set opening hours or admission arrangements. Reaching it means travelling to Pat Heung and continuing on foot into the village.

The building shows a rare religious dual heritage, having served both traditional Chinese ancestor worship practices and Catholic religious activities. This shift in functions within the same structure reflects Hong Kong's complex religious history in the first half of the 20th century.
