Regula Mühlemann (born 7 January 1986) is a Swiss operatic soprano. 　　Mühlemann was born in Adligenswil, Switzerland, and studied voice with Barbara Locher at the Academy of Music in Lucerne in 2010, where she graduated with honors with a Master of Arts. Her first appearances on the opera stage included the following roles: Maturina in Gazzaniga's Don Giovanni Tenorio, Barbarina in Mozart's The Marriage of Figaro, Papagena in Mozart's The Magic Flute, and Doralice in Scarlatti's Il trionfo dell'onore. 　　In Jens Neubert's film version of Weber's opera Der Freischütz, Mühlemann played the role of Ännchen and was praised by critics. The Neue Zürcher Zeitung saw her as "a discovery of the first order." In the 2010 and 2011 opera seasons, Mühlemann appeared at the Lucerne Theatre as soloist in several operas, such as The Magic Flute and Il trionfo dell'onore.
