Pulcinella is a 21-section ballet by Igor Stravinsky with arias for soprano, tenor and bass vocal soloists, and two sung trios. It is based on the 18th-century play Quatre Polichinelles semblables, or Four similar Pulcinellas, revolving around a stock character from commedia dell'arte. The work premiered at the Paris Opera on 15 May 1920 under the baton of Ernest Ansermet. The central dancer, Léonide Massine, created both the libretto and the choreography, while Pablo Picasso designed the costumes and sets. The ballet was commissioned by Sergei Diaghilev, impresario of the Ballets Russes. A complete performance takes 35–40 minutes. Stravinsky revised the score in 1965.

Diaghilev wanted a ballet based on an early 18th-century commedia dell'arte libretto and music then believed to have been composed by Giovanni Battista Pergolesi. This attribution has since been proved to be spurious. Some of the music may have been by Domenico Gallo, Unico Wilhelm van Wassenaer, Carlo Ignazio Monza and Alessandro Parisotti.

Conductor Ernest Ansermet wrote to Stravinsky in 1919 about the project. The composer initially did not like the idea of music by Pergolesi, but once he studied the scores, which Diaghilev had found in libraries in Naples and London, he changed his mind. Stravinsky adapted the older music to a more modern style by borrowing specific themes and textures, but interjecting his modern rhythms, cadences, and harmonies.

Pulcinella marked the beginning of Stravinsky's second phase as a composer, his neoclassical period. He wrote:

Pulcinella was my discovery of the past, the epiphany through which the whole of my late work became possible. It was a backward look, of course—the first of many love affairs in that direction—but it was a look in the mirror, too.

The ballet was revived and revised by New York City Ballet's balletmasters George Balanchine and Jerome Robbins for their 1972 Stravinsky Festival. They both danced in the performance, Robbins in the title role, and were joined in the premier by Francisco Moncion, who danced the role of The Devil.

Pulcinella is taken from a manuscript from Naples, dating from 1700, containing a number of comedies portraying the traditional character of the popular Neapolitan stage. This libretto was derived from Quatre Polichinelles semblables ("Four similar Pulcinellas").

The one-act ballet features Pulcinella, his girlfriend Pimpinella, his friends Furbo, Prudenza and Rosetta, and Florindo and Cloviello. The story starts with Florindo and Cloviello serenading Prudenza and Rosetta. The two women are unimpressed and reply by showering the suitors with water. Prudenza's father, a doctor, appears and chases them away.
