Bình Tuy was a province of South Vietnam. It now mostly corresponds to the western part of Bình ThuáºÂn, including Hàm Tân, Hàm ThuáºÂn Nam, Tánh Linh, ÃÂức Linh districts and La Gi town.
In 1976, it was merged with Ninh ThuáºÂn and Bình ThuáºÂn to form ThuáºÂn Hải province. After the latter was divided again into Ninh ThuáºÂn and Bình ThuáºÂn in 1991, Bình Tuy remained part of Bình ThuáºÂn province.
