A female character in the Gilbert and Sullivan masterpiece The Mikado. The role of Yum-Yum should be sung by a soprano.

Yum-Yum is the beautiful young ward of Ko-Ko, the Lord High Executioner, and she is preparing to be his bride when she reunites with Nanki-Poo, a childhood friend and the son of the Mikado, and falls in love with him instead. During the opera, Yum-Yum is distressed by not being able to marry her beloved, until finally Ko-Ko releases her from the engagement because he has fallen in love with Katisha.
Yum-Yum sings quite a bit during the midsection of the Mikado, but her biggest solo is "The Sun, Whose Rays."
