Francesco Andreini (c. 1548 – 1624) was an Italian actor mainly of commedia dell'arte plays. He began his career playing the role of the unsophisticated love-stricken young man. Later he played the role of Capitan Spavento ("Captain Fright"), a Pickwickian character of excessive fatigue. He died on January 1, 1624, in Mantua, Italy at the age of 76.
Francesco Andreini was the leader of the Gelosi commedia dell'arte troupe and had he not brought this type of theater elsewhere, it would not have made it further to the mainstream media and developed into multilingualism and oral and textual transmissions. His role of Capitano made its way into modern media with adapted versions solely based on the original Capitano. Francesco had an impact on today's theater and improvisation. 
Andreini was born at Pistoia. He was a member of the company of i Gelosi which Henry IV of France summoned to Paris for his bride, the young queen Marie de Medici, thus introducing the commedia dell'arte style to France.
He published his dialogue as Captain Spavento as "La bravura del Capitano Spavento." This dialogue takes place between the captain and his servant, Trappola. Francesco Andreini wrote four to five page boasts in his publication of his dialogue; although Andreini may have elaborated on these speeches in print, it is clear that he was trying to give the audience the intense verbosity within. Similarly, Andreini elaborates on the fact that the doctor was only talk, while the lovers could get carried away with themselves to any extent.
Andreini spoke a handful of languages including Italian, Turkish, English and French. He used a combination of these languages while performing. As Capitano, he often combined Italian and Turkish claiming it was Arabic. He also used Grammelot in his works and was one of the original inventors.
