Frederick Thomas Thorne (1862 – 26 November 1922), stage name Eric Thorne, was an English singer and actor in musical theatre and comic opera. His professional career began in 1884 with the D'Oyly Carte Opera Company where he worked for almost two years, and then he played roles for more than a decade at London theatres in plays, operettas and Edwardian musical comedies such as In Town and Gentleman Joe. From 1897, he became better known on tour, especially as Hilarius in La Poupée, Baron Popoff in The Merry Widow and Mr. Bulgar in The Dollar Princess. He was still performing in the early 1920s.
