Every Actor Who Has Voiced Optimus Prime In Transformers Movies & TV Shows

Many different actors have played the iconic Transformers character Optimus Prime over the years. The franchise, which is a collaboration between Hasbro in America and Takara Tomy in Japan, originally kicked off when the Takara Tomy toy lines Micro Change and Diaclone were rebranded in the West in 1984, accompanied by an animated series bringing the characters from the lines to life. Optimus Prime, whose Japanese name is Convoy, was one of the original Transformers characters during this rebrand launch.

Since it originated, the Transformers franchise has expanded to include a vast array of further toy lines and animated shows as well as additional multimedia properties including animated and live-action movies, comic books, video games, and more. Optimus Prime has continued to be one of the core characters of many of these iterations, and more than a dozen different actors have provided his voice over the years, with still others providing the voice of the character for toys, web series, and other related media.
