Dan Rolyat, born Herbert Taylor (11 November 1872 – 10 December 1927), was an English actor and singer. After an apprenticeship with a touring company he was engaged by the impresarios George Edwardes and Robert Courtneidge to play comic roles in musical comedy. He also played in variety shows and, later in his career, in farce.
Rolyat's greatest success was probably in the double role of John Smith and Simplicitas in The Arcadians (1909), first in the West End of London and then in the British provinces. While playing the role on tour he suffered a severe accident that threatened to end his career. He recovered and worked on until the mid-1920s when ill-health forced him to retire.
