Eugenio Giraldoni (20 May 1871, Marseille – 23 June 1924, Helsinki) was an Italian operatic baritone who enjoyed a substantial international career.
In 1900, he created the role of Baron Scarpia in Giacomo Puccini's Tosca.
He was the son of another leading baritone, Leone Giraldoni, and the soprano and violinist Carolina Ferni.
His mother gave him voice lessons and he made his opera debut in Barcelona, as Escamillo in Carmen, in 1891.
Giraldoni consolidated his career by appearing at various operatic venues in Italy and, in 1898, visiting South America.
Then, in 1900, he earned a place in operatic history when he created the part of Baron Scarpia in Tosca, at the Teatro Costanzi in Rome.
He also appeared in the first performance of Alberto Franchetti's La figlia di Jorio at Italy's foremost opera house, La Scala, Milan, in 1906.
He sang in Russia and Poland from 1901 until 1907 and at the Metropolitan Opera in New York City during the 1904–05 season.
He retired from the stage in Trieste in 1921 and died three years later in Finland, where he had gone to teach.
His last operatic appearance had been as the Father in Louise.
Giraldoni made a number of recordings prior to World War I, some of which have been reissued on CD.
