Benedetta Rosmunda Pisaroni (born Piacenza, 16 May 1793 – died Piacenza, 6 August 1872) was an Italian soprano who later became a contralto.
She was born as Benedetta Pisaroni to Giambattista Pisaroni and Luigia Pratti. Active on the operatic stage from 1811 to 1831, she suffered from smallpox in the early years of her career, which caused a change (downward) in her extended vocal range.
Appearing in Bergamo, Padua, Bologna, Venice, Milan, Rome, and eventually Paris in the 1810s and 1820s, she was closely associated with the operas of Gioachino Rossini and Giacomo Meyerbeer.
