Arthur Peronneau Hayne (March 12, 1788[1] – January 7, 1867) was a United States senator from South Carolina who belonged to the Democratic Party.

He pursued classical studies, engaged in business, and served in the War of 1812 as a first lieutenant at Sackets Harbor on Lake Ontario, major of cavalry on the St. Lawrence, and inspector general in 1814.

Thomas Duncan in Carlisle, Pennsylvania, was admitted to the bar and practiced, and served in the Florida War as commander of the Tennessee Volunteers and retired from the military in 1820.

When the frigate Chesapeake was attacked, he secured a commission as first lieutenant in a regiment of light dragoons, commanded by Colonel Wade Hampton of Revolutionary war fame.

In the famous Battle of New Orleans, Hayne selected the site for Jackson's defense and had much to do with repulsing the British and saving the city, as did Major Wade Hampton of Columbia.
