Gabriele Marchingiglio is an Italian voice actor, speaker, and singer, recognized for his extensive work dubbing anime, films, television series, and video games for the Italian market. Born on February 5, 1974, he is the father of fellow voice actor Lorenzo Marchingiglio.

His path to voice acting began with a background in music. Starting guitar at age ten and later taking singing lessons, he performed with rock bands and sang jingles for commercials, including one for Alpenliebe candies. This experience led him to pursue the spoken aspect of performance. He studied diction and acting at the Centro Teatro Attivo in Milan, which led to theatrical roles, including a tour performing in "Il fu Mattia Pascal," where he played the lead roles of Mattia and Adriano Meis. His work in theater eventually opened the door to dubbing, where he has since built a prolific career.

Marchingiglio is perhaps best known in the anime community for his long-standing role as the character Klein, also known as Ryōtarō Tsuboi, in the Italian adaptations of the Sword Art Online franchise. He has voiced this character across numerous installments, including the original series, Sword Art Online II, Sword Art Online: Alicization and its War of Underworld parts, the Extra Edition special, and the films Ordinal Scale and Progressive: Aria of a Starless Night. Another notable anime role is Feitan in the Hunter x Hunter OAV series, including Greed Island and G I Final.

His extensive voice portfolio spans a wide variety of other anime series. He is the voice of Issei Ryuudou in the Fate/stay night adaptations (Unlimited Blade Works and Heaven's Feel I. presage flower), Zetsu (the white half) in Naruto Shippūden and the film Road to Ninja, and Asato Ichijo in Vampire Knight and Vampire Knight Guilty. He has also contributed to series such as Beelzebub (as Salamander), Beyblade: Metal Masters (as Jack), Claymore (as Syd), Inazuma Eleven GO (as Ryoma Nishiki), and One Piece Film Red and Stampede (as Helmeppo).

Beyond anime, Marchingiglio's dubbing work encompasses a broad range of media. In live-action, he has voiced characters in films such as Sonic 3 - Il film (as a young Walters) and Hypnotic (as Brian Rawley), and in television series including Invasion (as Ahmed "Manny" Malik), Nip/Tuck (various roles), and the soap opera Tempesta d'amore (as Simon Konopka). He has also provided voices for animated series like Transformers: Robots in Disguise (as Quillfire) and Pac-Man and the Ghostly Adventures (as Clyde). In the realm of video games, he is well known for voicing Tommy Miller in the Italian versions of The Last of Us and The Last of Us Part II.

In addition to his dubbing career, Marchingiglio is an active speaker for television and radio commercials, having lent his voice to campaigns for major brands such as BMW, TIM, Vodafone, McDonald's, Samsung, Kinder Ferrero, IKEA, and Enel, among many others. He has also performed jingles for brands like Alpenliebe and Cartoon Network.
