His Majesty, or, The Court of Vingolia is an English comic opera in two acts with dialogue by F. C. Burnand, lyrics by R. C. Lehmann, additional lyrics by Adrian Ross and music by Alexander Mackenzie.
The work premiered at the Savoy Theatre in London on 20 February 1897, running for only 61 performances until 24 April 1897, despite a strong cast including George Grossmith, Ilka Pálmay, Scott Russell, Fred Billington, Florence Perry and Walter Passmore. The D'Oyly Carte Opera Company then toured the opera throughout 1897 alongside more familiar Gilbert and Sullivan works.
