Bình Định is a northern coastal province in the South Central Coast region, the Central of Vietnam. It borders Quảng Ngãi to the north, Phú Yên to the south, Gia Lai to the west and the East Sea to the east.

In Vietnam, South Central Coast and South Central Region are two terms which can refer to the same region or two regions that do not correspond to each other. South Central Coast consists of the independent municipality of Đà Nẵng and seven other provinces, which means South Central Coast doesn't include Central Highlands. Nevertheless, the term "South Central Region" can also be used to include Central Highlands as it is part of southern part of Central Vietnam.
