Pinckney's Treaty. noun. 1. an agreement in 1795 between Spain and the U.S. by which Spain recognized the 31st parallel as the southern boundary of the U.S. and permitted free navigation of the Mississippi to American ships.
Pinckney`s Treaty One of the most important diplomatic aims of the Washington administration was to secure recognition of American borders from the great powers. Britain did so in Jay's Treaty (negotiated in 1794 and ratified in 1795). France was unlikely to cooperate on any issue, given that the United States had failed to honor the alliance of 1778. Spain at this time held the prized port of New Orleans at the mouth of the Mississippi River.
