Pensacola Bay is a bay located in the northwestern part of Florida, United States, known as the Florida Panhandle.
The bay, an inlet of the Gulf of Mexico, is located in Escambia County and Santa Rosa County, adjacent to the city of Pensacola, Florida, and is about 13 miles (21 km) long and 2.5 miles (4 km) wide.
Pensacola Bay is formed and protected by Fairpoint Peninsula and the barrier island of Santa Rosa. The Pensacola Bay Bridge crosses the bay, connecting Pensacola to Gulf Breeze on the western end of the peninsula. The Gulf Islands National Seashore includes Santa Rosa Island, and encloses part of the bay. The Gulf Intracoastal Waterway runs through a section of the bay. Pensacola Bay leads into Escambia Bay to the north, and to the East Bay. Pensacola Pass connects the Bay to the Gulf of Mexico.
