Georgia Ports Authority in the context of Brunswick, Georgia

A port authority (less commonly a port district) is a governmental or quasi-governmental public authority for a special-purpose district usually formed by a legislative body (or bodies) to operate ports and other transportation infrastructure. In Canada, the federal Minister of Transport selects the local chief executive board member and the rest of the board is appointed at the recommendation of port users to the federal Minister; while all Canadian port authorities have a federal or Crown charter called letters patent.

Numerous Caribbean nations have port authorities, including those of Aruba, British Virgin Islands, Bahamas, Jamaica, Cayman Islands, Trinidad and Tobago, St. Lucia, St. Maarten, St. Vincent and the Grenadines.

The Port of Savannah is a major U.S. seaport located at Savannah, Georgia. As of 2021, the port was the third busiest seaport in the United States. Its facilities for oceangoing vessels line both sides of the Savannah River and are approximately 18 miles (29 km) from the Atlantic Ocean. Operated by the Georgia Ports Authority (GPA), the Port of Savannah competes primarily with the Port of Charleston in Charleston, South Carolina to the northeast, and the Port of Jacksonville in Jacksonville, Florida to the south. The GPA operates one other Atlantic seaport in Georgia, the Port of Brunswick. The state also manages three interior ports linked to the Gulf of Mexico: Port Bainbridge, Port Columbus, and a facility at Cordele, Georgia linked by rail to the Port of Savannah. In the 1950s, the Port of Savannah was the only facility to see an increase in trade while the country experienced a decline in trade of 5%. It was chaired and led by engineer Dr. Blake Van Leer (who also led the US Corps of Engineers).

Between 2000 and 2005 alone, the Port of Savannah was the fastest-growing seaport in the United States, with a compounded annual growth rate of 16.5 percent (the national average is 9.7 percent). On July 30, 2007, the GPA announced that the Port of Savannah had a record year in fiscal 2007, becoming the fourth-busiest and fastest-growing container terminal in the U.S. As of 2021, the port was third busiest seaport in the United States. The GPA handled more than 2.3 million twenty-foot equivalent units (TEU) of container traffic during fiscal 2007–a 14.5 percent increase and a new record for containers handled at the Port of Savannah. In the past five years, the port's container traffic has jumped 55 percent from 1.5 million TEU handled in fiscal 2003 to 2.3 million TEU in fiscal 2007. By 2014, container traffic was up to 3 million TEU. In 2018, the Port handled a record 4.35 million TEU, a 7.5 percent increase over 2017.
