Nina, o sia La pazza per amore (Nina, or Madly in Love) is an opera, described in 1790 as a commedia in prosa ed in verso per musica, in two acts by Giovanni Paisiello to an Italian libretto by Giovanni Battista Lorenzi after Giuseppe Carpani's translation of Benoît-Joseph Marsollier's Nina, ou La folle par amour, set by Nicolas Dalayrac in 1786. The work is a sentimental comedy with set numbers, recitative and spoken dialog. It is set in Italy in the 18th century. Nina was first performed in a one-act version at the Teatro del Reale Sito di Belvedere in Caserta, San Leucio on 25 June 1789. The revised and familiar two-act work was presented at the Teatro dei Fiorentini in Naples in the autumn of 1790.
