L'amico Fritz (Italian: [laˈmiːko ˈfrits]) is an opera in three acts by Pietro Mascagni, premiered in 1891 to a libretto by P. Suardon (Nicola Daspuro) (with additions by Giovanni Targioni-Tozzetti), based on the 1864 French novel L'Ami Fritz [fr] by Émile Erckmann and Alexandre Chatrian.

While the opera enjoyed some success in its day and is probably Mascagni's most famous work after Cavalleria rusticana, today it is performed far more rarely than Cavalleria, which remains Mascagni's only enduringly popular work outside Italy, where L'amico Fritz and Iris are still in the active repertoire.

The "Cherry Duet" between Fritz and Suzel in act 2 is the best known piece in the opera and is often performed separately in concert.

Other first performances include those in Hamburg on 16 January 1892 with Gustav Mahler conducting; in London on 23 May 1892 at the Royal Opera House, Covent Garden;[1] and in Australia on 19 October 1893 at the Princess's Theatre in Melbourne.

She joins the birthday celebration and is moved when the gypsy Beppe enters playing his violin.

Fritz returns and David mentions that he thinks he has found the right man for Suzel to marry.
