What is the Origin and Meaning of the Last Name Chau?

The surname of Chau seems to originate from the country of Vietnam and may derive from the common Chinese surnames Chow or Zhou. As a surname Zhou likely derives from the descendants of the Zhou Dynasty (1046 - 256 BC).

Lasting some 790 years, the Zhou was the longest-reigning Dynasty in China. The lineage of the Dynasty in myth dates back to the miraculous birth of Qi, “The Abandoned One.” Qi became a cultural hero and his descendants moved around a great deal. At one point parts of the clan settled in Zhou within the Wei River Valley.

Chau then is derived from Zhou which in myth at least was the name of a place making it a habitual surname. The greatest concentration of the Chau version of this name is found in Vietnam so it is logical to assume that this particular variant originates from that country. Centuries of Chinese occupation in Vietnam may explain a switch toward a different spelling or pronunciation of Zhou.

Chau Van Tiep (1738–1784) was a notable general serving under the first emperor of the unified Vietnamese monarchy Nguyen Anh. Born in Phu Yen, Chau was a master of martial arts and spoke both Siamese and Khmer.
