Mario Tiberini (8 September 1826 – 16 October 1880) was an Italian tenor who sang leading roles in the opera houses of Europe and the Americas in a career spanning 25 years.
Known for his advanced singing technique and dramatic ability, he sang the role of Alvaro in the premiere of the revised (and now standard) version of Verdi's La forza del destino and created several roles in operas by lesser-known composers, including the title role in Faccio's Amleto.
