Giovanni Battista Rubini (7 April 1794 – 3 March 1854) was an Italian tenor, as famous in his time as Enrico Caruso in a later day. His ringing and expressive coloratura dexterity in the highest register of his voice, the tenorino, inspired the writing of operatic roles which today are almost impossible to cast. As a singer Rubini was the major early exponent of the Romantic style of the bel canto era of Vincenzo Bellini and Gaetano Donizetti.
