Hung Shing Temple, Kau Sai Chau, Chinese temple and declared monument in Kau Sai Chau, Hong Kong.

Hung Shing Temple on Kau Sai Chau is a Qing-dynasty temple with a two-hall, three-bay plan. A screen door stands in the entrance hall, and the main hall's altar holds Hung Shing, Caibo Xingjun and Shui Xian Ye. The temple was repaired in 1999 to restore its original appearance.

A stone tablet in the temple suggests it was first built in 1889, the 15th year of the Guangxu reign. It was repaired in 1999 with funding from the Hong Kong Jockey Club, and the work was completed the following year. On 15 November 2002 it was declared a monument by the Antiquities and Monuments Office.

Each year at the Hung Shing Festival, residents gather in the open space in front of the temple for large celebrations. Inside, the main altar honours Hung Shing together with Caibo Xingjun, the god of wealth, and Shui Xian Ye, the water deity.

The temple is accessible only by private boat, as regular ferry services to the island are limited and advance arrangements are necessary. Visitors should plan their journey ahead and account for weather conditions that may affect travel to this remote location.

The temple's restoration project received the Outstanding Project Award from UNESCO Asia-Pacific Heritage Awards for Cultural Heritage Conservation in 2000. This recognition highlighted the skilled craftsmanship involved in carefully returning the structure to its historical condition.
