France–Suriname border

The France–Suriname or French Guiana–Suriname border is a roughly 520-kilometer line that internationally separates French Guiana (an overseas department of France) and Suriname. In 1915, the border was decided upon, following the Maroni River for its northern portion, but the southernmost section of the border remains disputed despite numerous attempts to officially and formally demarcate it. Particularly, the debate is over which Lawa River sub-tributary should be considered the international border between the two nations. In addition to the land border, France, through its overseas department, and Suriname, share an approximately 200-nautical mile maritime border that was fully demarcated in 2017.
