St. Andrew Bay, colloquially called St. Andrews Bay, is a bay located in Bay County in the panhandle of Florida. It is a 69,000-acre estuary located in northwest Florida. It is relatively deep, and of relatively high salinity due to the low freshwater inflow provided by only a few spring-fed creeks (the most significant being Econfina Creek, fed by Wiliford and Pitts Springs). The bay is named for Saint Andrew. Panama City, the county seat of Bay County, is located on the bay. The Atlanta & St. Andrews Bay Railway, which ran from Panama City to Dothan, Alabama (and still exists as a smaller short line), was also named for the bay.
