Two Merry Monarchs is an Edwardian musical comedy in two acts with a book by Arthur Anderson and George Levy, lyrics by Anderson and Hartley Carrick, and music by Orlando Morgan. It opened at the Savoy Theatre in London on 10 March 1910, under the management of C. H. Workman, and ran there for 43 performances. It starred Workman, Robert Whyte Jr., Lennox Pawle, Daisy le Hay and Roland Cunningham. The work was the last piece that could be considered a Savoy opera.

Savoy opera was a style of comic opera that developed in Victorian England in the late 19th century, with W. S. Gilbert and Arthur Sullivan as the original and most successful practitioners. The name is derived from the Savoy Theatre, which impresario Richard D'Oyly Carte built to house the Gilbert and Sullivan pieces, and later those by other composer–librettist teams. The great bulk of the non-G&S Savoy Operas either failed to achieve a foothold in the standard repertory, or have faded over the years, leaving the term "Savoy Opera" as practically synonymous with Gilbert and Sullivan. The Savoy operas were seminal influences on the creation of the modern musical.
