Hậu Giang ( listen) is a province of Vietnam, in the Mekong Delta region in the southern part of that country. Vị Thanh is the capital.

Until 1975, the province of Hậu Giang included the city of Cần Thơ; that city was the capital of the province. In 1975, the province was renamed Cần Thơ Province, with the city of Cần Thơ still the capital. In late 2004, Cần Thơ and some surrounding cities became Cần Thơ Municipality (Thành Phố Cần Thơ). The remainder of Cần Thơ Province became Hậu Giang Province.
