Au Tak (also spelled Au Tack; ; 1840–1920) or Au Chak-mun () was a Hong Kong entrepreneur. He was the proprietor of a furniture shop and the property developers in Central District on Hong Kong Island. He used to be the director of Tung Wah Hospital.

In 1912, Au went into partnership with his father-in-law Sir Kai Ho to form a company to develop a piece of land formed by land reclamation in Kowloon Bay. It was planned to build a residential garden estate, but the plan failed and the company went into liquidation in 1924, after both Au and Ho had died. In 1925, the land was taken over by the British Hong Kong Government as the use of the airport.
