Kate Condon (February 4, 1877 – May 27, 1941) was an American contralto who performed in light and grand operas on Broadway and in opera houses over the first two decades of the twentieth century. Condon's first appearance in a major production on the New York stage came in November 1900, playing Siebel in the English Grand Opera Company's production of Charles Gounod's Faust with the Metropolitan Opera. She had previously been a member of the Castle Square Company in Boston and would later perform on Broadway and elsewhere with such stars as Jefferson De Angelis, De Wolf Hopper, Fritzi Scheff, and Tyrone Power, Sr. Her first role on Broadway was Molly O'Grady in The Emerald Isle in 1902. Among other Broadway appearances, in 1913 she appeared in revivals of two Gilbert and Sullivan operas. Condon crossed the Atlantic during the First World War to entertain troops serving with the American Expeditionary Force in France. In 1917–18, near the end of her career, her last Broadway role was in a successful revival of the musical, Chu Chin Chow.
