Thomas Amos Rogers Nelson (March 19, 1812 – August 24, 1873) was an American attorney, politician, and judge, active primarily in East Tennessee during the mid-19th century.
He represented Tennessee's 1st Congressional District in the 36th U.S.
Congress (1859–1861), where he gained a reputation as a staunch pro-Union southerner.
He was elected to a second term in 1861 on the eve of the Civil War, but was arrested by Confederate authorities before he could take his seat.
As early as the 1830s, Nelson had gained a reputation as an effective Whig Party campaigner, but due to family considerations, he did not run for office until 1859.
In December of that year, Nelson gained international renown for an explosive anti-secession speech he delivered before Congress.
As president of the East Tennessee Convention, Nelson campaigned to keep Tennessee in the Union, but maintained a neutral position after his arrest.
After the war, Nelson opposed the radical initiatives of his long-time friend, Governor William G.
Brownlow, and used his position on the state supreme court to overturn many of Brownlow's policies.
Nelson served on the defense team of President Andrew Johnson during Johnson's impeachment trial in 1868, and was elected to the Tennessee Supreme Court in 1870.
