Francesca Lebrun, née Danzi (24 March 1756 – 14 May 1791), was a noted 18th-century German singer and composer.
She was born Franziska Dorothea Danzi in Mannheim, Germany.
Her father was the Italian-born cellist Innocenz Danzi and her younger brother was the composer and cellist Franz Danzi (1763–1826).
She was renowned for her vocal dexterity and highly sought after by notable contemporaries, such as Anton Schweitzer, Ignaz Holzbauer, and Antonio Salieri, for the lead roles in their most challenging opuses.
Her talent extended beyond the stage to the manuscript tablet and the keyboard; twelve sonatas of hers for fortepiano and violin survive, six of which have been recorded.
