Mark Anthony Cooper (April 20, 1800 – March 17, 1885) was an American politician, businessman and lawyer who was a U.S. Representative from Georgia.

During the war, Cooper distinguished himself and reiterated his belief in states' rights by refusing to turn over 3,000 pounds of bacon to federal authorities because it was sent to feed Georgia militia men.

He returned to the U.S. Congress in 1842 after winning election as a Democrat to fill the remainder of the term of William Crosby Dawson, who had resigned in 1841 to run for the Governor of Georgia.

Cooper was reelected to that congressional seat in the general election in 1842; however, he resigned in 1843 to run an unsuccessful candidacy for Governor.

During his time as an attorney, Cooper was a lender essentially functioning as the local bank in Eatonton.

Most of the town of Etowah was destroyed during Sherman's March on Atlanta; however, the iron furnaces themselves were left standing.
