Andreas Schaerer (born 17 December 1976) is a Swiss jazz vocalist and composer, performing internationally, and an academic teacher.

He founded the sextet 'Hildegard Lernt Fliegen' and collaborated with notable international musicians, including Bobby McFerrin for the improvised opera Bobble.

[2] In 2017, he invited by Michael Wollny, then artist in residence of the Rheingau Musik Festival, to play at the Kurhaus Wiesbaden a concert with also saxophonist Émile Parisien and accordionist Vincent Peirani.

A reviewer noted that he is interested, as the others, to expand the spectrum of his "instrument", and described his excentric-capricious vocal improvisations bordering percussive sounds, and a sometime "sacred" touch in the high register ("exzentrisch-kapriziösen Vokalimprovisationen auf der Grenze zum pointiert perkussionistischen Geräuschemacher über eine mitunter sakrale Anmutung in den Höhen").

He is noted for his extensive scat singing, and his wide variety of vocal timbres which include opera, crooning, soul, and sprechgesang.
