Marco Joannucci was an Italian voice actor active primarily in the 1980s, known for his contributions to the dubbing of numerous anime series for Italian television. Born in Rome in 1956, he was a graduate of the Pietro Sharoff acting school in Rome. His career in voice acting spanned approximately from the early 1980s until his departure from the field in the early 1990s.

Joannucci provided voices for a wide array of characters in anime that were staples of Italian children's programming. One of his earliest and most notable roles was as the voice of the older protagonist Sugar Peper in the series Forza Sugar, the Italian adaptation of Ganbare Genki. He also took over the role of Jacky in the robot series Vultus 5, the Italian localization of Voltes V, succeeding the character's first voice actor. Another significant role was that of the hero Beppe Domani, who transforms into Yattodetaman, in the series Calendar Men, part of the popular Time Bokan series.

His voice was frequently heard in other major anime of the era. He was the second voice for the character Guglia in the initial Italian edition of Doraemon, taking over from Massimo Corizza. In L'Uomo Tigre, il campione, he voiced both Ken Takaoka and the character Kenta. His other anime credits include the first voice for Yattaman and Yattacan in the series Yattaman, Bero in Bem, Paul Cabor in Ransie la strega, Captain Thomas in Gigi la trottola, Numajos in Ulysse 31, and Gustavo in Alla scoperta di Babbo Natale.

His work in anime was part of a broader voice acting career that included roles in live-action films and television. He dubbed actors such as Steve Guttenberg, Kevin Bacon, and Jackie Earle Haley in various films and appeared in television series. Joannucci's career was marked by recurring collaborations with the Roman dubbing industry of the time, frequently working with the dubbing director Giovanni Brusatori and studios like CRC (Cooperativa Rinascita Cinematografica) and Play World Film, which were responsible for the Italian adaptations of many of the anime series he voiced. After leaving the voice acting profession, he transitioned to a career as an author of audio-descriptive texts.
