Archibald Dixon (April 2, 1802 – April 23, 1876) was a U.S. Senator from Kentucky. He represented the Whig Party in both houses of the Kentucky General Assembly, and was elected the 12th Lieutenant Governor of Kentucky in 1844, serving under Governor William Owsley. In 1851, the Whigs nominated him for governor, but he lost to Lazarus W. Powell, his former law partner.
Dixon represented Henderson County at the Kentucky constitutional convention of 1849. In this capacity, he ensured that strong protections of slave property were included in the Kentucky Constitution of 1850. Later, the General Assembly chose Dixon to fill the unexpired Senate term of Henry Clay. He served from September 1, 1852, to March 3, 1855, and did not stand for re-election. During his short tenure, Dixon's major accomplishment was convincing Stephen Douglas to include language in the Kansas-Nebraska Act that explicitly repealed the Missouri Compromise's prohibition on slavery north of latitude 36°30'.
