The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately 1050 miles (1700 kilometers) from Carrabelle, Florida, to Brownsville, Texas.

The waterway provides a channel with a controlling depth of 12 feet (3.7 meters), designed primarily for barge transportation. Although the U.S. government proposals for such a waterway were made in the early 19th century,[1] the Gulf Intracoastal Waterway was not completed until 1949.[2]
