Thomas Todd (January 23, 1765 – February 7, 1826) was an Associate Justice of the Supreme Court of the United States from 1807 to 1826. Raised in the Colony of Virginia, he briefly served in the American Revolutionary War before completing his education and moving westward, where he participated in the founding of Kentucky. There he practiced law as well as served as a clerk and judge, before becoming a Supreme Court justice. He married twice and had a total of eight children. Todd joined the U.S. Supreme Court in 1807 and his handful of legal opinions there mostly concerned land claims. He was labeled the most insignificant U.S. Supreme Court justice by Frank H. Easterbrook in The Most Insignificant Justice: Further Evidence, 50 U. Chi. L. Rev. 481 (1983).
