萨沃伊歌剧（Savoy Opera），19世纪后期英国流行的歌剧，是一种带有讽刺意味的喜剧。

由英国音乐剧作曲家阿瑟·萨利文爵士（Sir Arthur Sullivan）与剧作家威廉·S·吉尔伯特（W. S. Gilbert）合作的歌剧称之为“萨沃伊歌剧”，两人合称“吉尔伯特与萨利文”。吉尔伯特喜欢装傻，爱讽刺人，一改过去歌剧严肃的风格，剧中将很多现实中荒诞的一面演得合情合理。萨沃伊歌剧此名称的由来源自「萨伏依剧院」。该剧院位于英国伦敦西敏市的河岸街。它开业于1881年10月10日，由理乍得·多伊利·卡特(Richard D'Oyly Carte)兴建于昔日的萨沃伊宫遗址，萨沃伊剧院专门演出吉尔伯特与萨利文的喜歌剧，例如《日本天皇》。因此后人将此类于萨沃伊剧院演出的剧种称为萨沃伊歌剧。

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 (in both senses) were seminal influences on the creation of the modern musical.
