The Hong Kong Chinese Christian Churches Union (HKCCCU) () is an inter-denominational organization in Hong Kong with Chinese Christian churches as its membership base. It was founded by seven Protestant denominations in 1915, and now has become one of the largest Christian organizations in Hong Kong, with more than 400 member churches.

In 1948, it was registered as a legal organization (Hong Kong Register of Societies No.1025) . The union has now developed to 414 member churches from different denominations and independent churches, with a total number of over 400,000 believers. All member churches, regardless of denomination or size, enjoy equal rights and obligations. Except for the regulations set out in its constitution, the Union does not interfere with the internal administration of the member churches.
