Carlo Pietro Tagliabue (January 13, 1898 in Mariano Comense – April 6, 1978 in Monza) was an Italian baritone. After studies with Leopoldo Gennai and Annibale Guidotti he made his debut in Lodi, Lombardy, in Loreley and Aida. His debuts in Genoa (1923), Torino, La Scala (1930), Rome (1931), and Naples (1931) were all in Tristan und Isolde (sung in Italian). He also performed in Wagner's Götterdämmerung, Tannhäuser and Lohengrin. However, Tagliabue would go on to excel in the Verdian repertoire, especially La forza del destino, Aida, Rigoletto, La traviata, Nabucco, and Otello. He created the role of Basilio in Respighi's La fiamma in 1934.
