Giancarlo Alessandrini (born March 20, 1950) is an Italian comic artist.
Born in Iesi, Alessandrini graduated from Ancona's Art Institute and begins drawing comics professionally in 1972 for Il Corriere dei Ragazzi with the story Il Cifrario del Maggiore Martin written by Mino Milani. The following year he produced ten episodes of the fantasy series Anni 2000, again written by Milani, and twelve episodes of Lork Shark two years later.
In 1975 Alessandrini joined Studio Giolitti and drew several war stories for British publisher Fleetway. He continued his cooperation with Il Corriere dei Ragazzi, drawing two episodes of the series Il Maestro, written by Milani. When in 1976 the editor refused some of the pages for the series asking him to redraw them, Alessandrini decided instead to leave.
He then drew Eva Kant for the Italian edition of Cosmopolitan. The series is written by Alfredo Castelli and marks the first of a series of collaborations. In 1976 the two produced L'uomo di Chicago for Bonelli's Un Uomo un'Avventura, then in 1978 they worked together on Allan Quatermain for Supergulp, published by Mondadori and on Mister No, again for Bonelli.
Starting in 1977, Alessandrini worked on the western series Ken Parker, written by Giancarlo Berardi. His cooperation will continue until 1980, resulting in six 96 pages episodes. That same year Alessandrini started working for Catholic weekly Il Giornalino, where he drew some episodes of the series Ai confini dell'avventura and Storie di tutti i tempi. In 1981 he created with scriptwriter Claudio Nizzi the series Rosco & Sonny, using himself as a model for Sonny's features.
