Thomas Richard Whitney (May 2, 1807 – April 12, 1858) was a nineteenth-century politician and writer from New York.
He pursued classical studies and worked as a jeweler, engraver and watchmaker before turning to journalism and politics as editor of the New York Sunday Times.
He was a member of the Silver Gray (pro-Millard Fillmore and anti-William H. Seward) faction of the Whig Party, and served as Clerk of the city's Board of Assistant Aldermen.
During the extended balloting for Speaker of the House in December 1855, Whitney consistently received one vote, that of Henry Mills Fuller.
Whitney became ill during his term in Congress, and traveled to South America in an effort to regain his health.
