There are two types of coastline: saltwater coastlines on the shore of the ocean (or a gulf, bay, or other inlet) and lake coastlines (as along the great lakes, brackish estuaries, or other non-river waterfront). 30 US states have one type or both.

23 US states have saltwater coasts (ocean, gulf, bay).

There are 14 (or fifteen, with Pennsylvania) on the Atlantic, and 4 more on the Gulf of Mexico (along with Florida). There are 5 on the Pacific Coast, including Alaska and Hawaii. Alaska also has coastline on the Arctic Ocean. Pennsylvania is sometimes included as the 24th on the basis of its Delaware River estuary, a length of about 57 miles.

8 states (including Pennsylvania and New York) have Great Lakes coastlines.


Here are the figures for the US states that have saltwater (ocean) coasts:

Alabama 53 miles (shoreline 607 miles)
