Paul Alfred Rubens was an English songwriter and librettist who wrote some of the most popular Edwardian musical comedies of the early twentieth century. He contributed to the success of dozens of musicals.

Edwardian musical comedy was a form of British musical theatre that extended beyond the reign of King Edward VII in both directions, beginning in the early 1890s, when the Gilbert and Sullivan operas' dominance had ended, until the rise of the American musicals by Jerome Kern, Rodgers and Hart, George Gershwin and Cole Porter following the First World War.
