  • The following list of the states with the 10 longest coastlines in the United States is arranged by length.
  • The bodies of water that they border have been included for reference.
  • Note on the figures: Numbers can vary across sources, as the length of a coastline depends on how detailed the measurements are around each inlet and bay and whether all the islands are counted (such as in Alaska and Florida’s figures). Figures can also change often due to flooding, erosion, and rising sea levels. The statistics here come from World Atlas.com.

Alaska

Length: 33,904 mi (54,563 km)
Bordering: The Pacific Ocean and ​the Arctic Ocean
If you measure just the coast, Alaska has 6,640 miles of coastline; if you measure all inlets and bays, it’s more than 47,000 miles.

 

Florida

Length: 8,436 mi (13,576 km)
Bordering: The Atlantic Ocean and the Gulf of Mexico
No matter where you are in Florida, you’re never more than an hour and a half from the beach. 

 

Louisiana

Length: 7,721 mi (12,426 km)
Bordering: The Gulf of Mexico 
The United States Geological Survey has found that Louisiana’s barrier islands erode up to 66 feet (20 m) per year; these protect fragile wetlands from being inundated with saltwater, protect the coast from erosion, and dampen the force of waves that come inland from hurricanes and storms.

 

Maine

Length: 3,478 mi (5,597 km)
Bordering: The Atlantic Ocean 
If all the miles of Maine’s 3,000+ islands were taken into account, Maine would have more than 5,000 miles of coastline.

California

Length: 3,427 mi (5,515 km)
Bordering: The Pacific Ocean
Most of California’s coast is rocky; the beaches made famous in all those ’60s movies are only along the southern coast of the state.
