Stefano Thermes is an Italian actor and voice actor born in Rome on November 9, 1969. He is primarily known for his work providing the Italian voices for numerous characters in anime series and films, as well as in live-action and video game adaptations. His career in dubbing encompasses a wide range of roles, from protagonist mentors to powerful antagonists.

Thermes has lent his voice to a variety of notable anime characters. Among his most recognized roles are Leif Ericson in the historical epic Vinland Saga, the intimidating restaurant owner Tanba in the dark fantasy Dorohedoro, and the mysterious Shide in Summer Time Rendering. He also voiced the character Boss in the film Mai Mai Miracle and Sindaco Hummingbat in the series Spriggan. His work extends beyond anime series to include animated films, such as his role in Dragon Quest Your Story, where he voiced Skriterioska.

In addition to his work in animation, Thermes is active in dubbing live-action productions and video games into Italian. His credits in this area include providing the Italian voice for Grewishka in the film Alita: Battle Angel, for Führer King Bradley in the live-action Fullmetal Alchemist films, and for Saigo in Shin Godzilla. He has also voiced characters in live-action series, such as Genzo in the Netflix adaptation of One Piece. His video game work includes voicing Optimus Prime in the Italian version of Transformers: Battlegrounds.

While specific information on recurring collaborations with particular directors or dubbing studios is limited, his body of work shows a consistent presence in Italian dubs produced for major platforms and distributors. His role in Dorohedoro, for instance, was dubbed at SDI Media in Rome under the direction of Monica Bertolotti. A notable, if unusual, point in his career came from an error in the credits of Transformers: Battlegrounds, which mistakenly included a memorial for him, despite him being alive at the time of the game's release.
