Ruth Vincent (22 March 1877 – 4 July 1955) was an English opera singer and actress, best remembered for her performances in soprano roles of the Savoy Operas with the D'Oyly Carte Opera Company in the 1890s and her roles in the West End during the first decade of the 20th century, particularly her role as Sophia in Tom Jones.
Vincent joined D'Oyly Carte in 1894 in the chorus at the age of 17. She began to play small roles in 1896, taking on larger roles in Gilbert and Sullivan revivals the following year and soon creating leading roles including Iza in The Grand Duchess of Gerolstein (1897–98), Laine in The Beauty Stone (1898) and Princess Laoula in The Lucky Star (1899). She also continued to sing leading roles in Gilbert and Sullivan revivals, including Casilda in The Gondoliers and Aline in The Sorcerer in 1898 and Josephine in H.M.S. Pinafore in 1899. Unhappy to be passed over for the leading soprano role in The Rose of Persia, Vincent left the company near the end of 1899.
After this, Vincent went on to a substantial career in Edwardian musical comedies, opera and concert singing. She created leading West End roles in Véronique (1904–05), Tom Jones (1907), The Belle of Brittany (1909) and several others, and she also performed on Broadway. From 1910, she began a grand opera career at Covent Garden and Drury Lane and then toured in oratorio and concerts and also in variety shows, performing until 1930.
