Almerindo Spadetta (c. 1822—April 1894) was a prolific opera librettist active in Naples. He worked as a stage manager at the Teatro San Carlo, Teatro Nuovo, and Teatro del Fondo in Naples for over 40 years and wrote numerous libretti (mostly in the opera buffa genre) for composers associated with those theatres. His most enduring work was the libretto for Nicola De Giosa's Don Checco, one of the last great successes in the history of Neapolitan opera buffa.
