On 15 March 2017, the maritime boundary between the island nation of Antigua and Barbuda and the French overseas collective of Saint Barthélemy was established. The boundary extends for 43 nautical miles and is defined by a series of seven loxodromes connecting eight points. In the north the boundary continues from point A1 along a specified azimuth until reaching an established tripoint with the United Kingdom (Anguilla) and in the south along another azimuth before reaching the maritime space of Saint Kitts and Nevis.

This maritime boundary Agreement also established the boundary between Antigua & Barbuda and France (Guadeloupe).
