The maritime boundary between France and the Bailiwick of Jersey, a Crown Dependency of the United Kingdom, was delimited by virtue of a bilateral agreement that was reached in 2000. The line is based on the application of the equidistance methodology. The two boundary terminuses are tripoints with the Bailiwick of Guernsey. The boundary is 80 nautical miles long and generally forms a “U” shape around Jersey’s south facing coast. Both Jersey and Guernsey are fully enclaved within French waters.

France and the United Kingdom also have an English Channel maritime boundary as well as one with Guernsey.
