Samuel Perry "Powhatan" Carter (August 6, 1819 - May 26, 1891) was a Brevet Major General in the Union Army during the U.S. Civil War.
Originally a U.S. Naval Academy graduate in 1846, he saw service in the Navy up to the Civil War. Never resigning from the Navy, he was detached to the Union Army by the War Department, and appointed a Brigadier General of volunteers. The Navy kept his promotions up during that period, and he eventually attained the rank of Rear Admiral shortly after he retired.
