Bon Secour (postal zip code 36511) is an unincorporated community in Baldwin County, Alabama, United States. It lies along the eastern coastline of Bon Secour Bay (a contiguous bay that sits along the eastern edge of Mobile Bay). Bon Secour is over 35 miles (56 km) due east of the Alabama–Mississippi state line, near Gulf Shores, and over 45 miles (72 km) west of Pensacola, Florida. The name "Bon Secour" derives from the French phrase meaning "safe harbor" due to the secluded location on the inside coast of the Fort Morgan peninsula of southern Alabama.
Bon Secour lies on the Bon Secour River. Elevation is 10 feet (3.0 m) above sea level. The estuarial river system empties into Bon Secour Bay at Mobile Bay.
The estimated population of the town is 743 in 2010, up from 302 in 2000 (see detailed Demographics below). However, since Hurricane Ivan, single-family housing developments and the population have continued to grow. It is part of the Daphne-Fairhope-Foley micropolitan area.
Bon Secour is sometimes mentioned in hurricane report statistics, for the region, since Bon Secour is the easternmost town inside the coastline of Mobile Bay when entering the bay from the south, indicating weather and tide conditions for the population at the southeast end of Mobile Bay, nearest the entrance to the Gulf of Mexico. By contrast, Mobile, Alabama is located near the (diagonally opposite) north end of Mobile Bay, much farther from the Gulf tide and hurricane storm surges.
