Basil Willett Charles Hood was a British dramatist and lyricist, perhaps best known for writing the libretti of half a dozen Savoy Operas and for his English adaptations of operettas, including The Merry Widow.

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.
