Filippo Andrea Francesco Coletti (11 May 1811 – 13 June 1894) was an Italian baritone associated with Giuseppe Verdi. Coletti created two Verdi roles: Gusmano in Alzira and Francesco in I masnadieri. Verdi revised the role of Germont in La traviata for Coletti, whose interpretation re-defined the role as it is known today. Coletti was, with Antonio Tamburini (1800–1876) and Giorgio Ronconi (1810–1890), one of the three leading baritones of 19th century Italy, an early model of a 'Verdi baritone'.
