Five States Share the Gulf Coastline

The Gulf of Mexico borders the following five U.S. states, listed from east to west:

1. Florida – The panhandle and western peninsula form a long, curved coastline.
2. Alabama – A relatively short but economically vital stretch (Mobile Bay).
3. Mississippi – Includes the Mississippi Sound and barrier islands.
4. Louisiana – Complex deltaic coast with vast wetlands, bayous, and the Mississippi River Delta.
