Aristodemo Giorgini (30 June 1877 – 19 January 1937) was an Italian opera singer who sang leading lyric tenor roles on the stages of Europe and North America during his 25-year career.

He made numerous recordings in the early 20th century and was described by Gramophone Magazine as possessing "a sweet, steady, well-placed voice and a style distinguished by the purity of its legato.

He made an unsuccessful stage debut in Naples in 1903 after which he pursued further private vocal studies with Massimino Perilli.

[6][3][7][8] Giorgini's performances in the 1920s included Faust in Mefistofele at the Teatro dal Verme in 1920 and Cavaradossi in Tosca at the Vienna Staatsoper in 1921 as well as a concert tour through Belgium and Holland in 1923.

The operas represented include L'Africaine, Tosca, Fedora, I puritani, La sonnambula, Les pêcheurs de perles, Luisa Miller, Adriana Lecouvreur, Werther, Il Barbiere di Siviglia, Don Pasquale, Lucia di Lammermoor, Pagliacci, and La fanciulla del West.
