List of U.S. States by coastline - wikipedia List of U.S. States by coastline States shaded dark blue have ocean coastline. * States shaded light blue have Great Lakes coastline. * States shaded white have no coastline. * New York has both ocean and Great Lakes coastline This is a list of U.S. states ranked by their coastline length. Thirty states have a coastline : twenty - three with a coastline on the Arctic, Atlantic, and / or Pacific Ocean, and eight with a Great Lakes coastline ; New York has coasts on both. States with no coastline are not included. Two separate measurements are used : method 1 only includes states with ocean coastline and excludes tidal inlets ; method 2 includes Great Lake coastline and the extra length from tidal inlets. For example, method 2 counts the Great Bay as part of New Hampshire 's coastline, but method 1 does not. The resulting figures differ significantly due to the ambiguity inherent in all attempts at measuring coastlines, as expressed in the coastline paradox. The data for method 1 were retrieved from a CRS Report for Congress using data from U.S. Department of Commerce, National Oceanic and Atmospheric Administration, The Coastline of the United States, 1975. This is based on measurements made using large - scale nautical charts. The figure for Connecticut was arrived at separately and may not reflect the correct comparative distance. These numbers exclude the Great Lakes coastlines. The data for method 2 are from a list maintained by the Office of Ocean and Coastal Resource Management of the National Oceanic and Atmospheric Administration ( NOAA ). The state coastline lengths were computed by an unspecified method that includes tidal areas not included in the first method. These numbers also include the Great Lakes coastlines, which do not have similar tidal areas. The lists do not include Vermont, a portion of whose border with New York state is Lake Champlain, the sixth - largest lake in the United States. The lake is also not included in New York 's total.
