Choctawhatchee Bay is a bay in the Emerald Coast region of the Florida Panhandle. The bay, located within Okaloosa and Walton counties, has a surface area of 334 square kilometres (129 sq mi).
It is an inlet of the Gulf of Mexico, connected to it through East Pass (also known as Destin Pass).
It also connects to Santa Rosa Sound in Fort Walton Beach, Florida to the west and to St. Andrews Bay in Bay County to the east, via the Gulf Intracoastal Waterway. East Pass is the only outlet of the bay flowing directly into the Gulf of Mexico.
The Choctawhatchee River flows into Choctawhatchee Bay, as do several smaller rivers and streams.
The Mid-Bay Bridge crosses the bay, connecting the city of Destin to Niceville, Florida. Second bridge across the bay is the Judge Clyde B. Wells Bridge.
