Border Delimitation

Border lines

The border of the Dominican Republic with Haiti is conventional (established by equal negotiations between the bordering States). The border line measures 382.8 kilometers in length and extends from the mouth of the Dajabón river (also named Masacre), in the northeast of the island, to the mouth of the Pedernales river, in the southeast.

The border was established on June 3, 1777, when the Treaty of Aranjuez was signed in the Spanish city of the same name.
