Corrado Zambelli (3 June 1897 in Bondeno (Fe) – 1 September 1974 in Bologna) was an Italian classical bass who had an active international singing career in operas and concerts from the 1920s through the 1950s.
Born in Bondeno (Fe), he studied singing with Alessandro Vezzani at the Liceo musicale di Bologna (now the Conservatorio Giovanni Battista Martini).
On the international stage, Zambelli toured Australia with an Italian opera troupe in 1930.
He was committed to the Royal Opera House in London in 1938–1939, performing such roles as Colline in La Bohème, Ramfis in Aida, Sparafucile, and Timur in Turandot.
Zambelli was active as a teacher of singing in Bologna both during his career and after his retirement from the stage.
