Takeshi Maeda is a Japanese actor and voice actor born on January 10, 1975, in Tokyo, Japan. He is a graduate of the College of Art at Nihon University. Maeda is affiliated with the talent agency Herringbone and is a member of the theatre troupe BQMAP, highlighting a career that balances voice work with stage performance.

His voice is characterized as a low tenor, often used for serious, hot-blooded, or quietly intense characters. However, he is equally renowned for his comedic roles, particularly his ability to deliver gags with a straight-faced, serious voice, creating a unique and beloved comedic effect. This versatility is a hallmark of his career.

Maeda is perhaps best known for his multiple roles in the long-running gag anime series Gag Manga Biyori (known in English as Gag Manga Biyori), where he has voiced a wide array of characters across different seasons. His performances in this series, which include the historical figure Prince Shōtoku, the poet Kawahara no Sōra, and the bear character Kumakichi, are considered signature roles. He is also widely recognized by fans of the Yu-Gi-Oh! franchise for his role as Ryo Marufuji in Yu-Gi-Oh! Duel Monsters GX.

In addition to his work under his own name, Maeda uses the pseudonym Renaissance Yamada for appearances in adult-oriented games. He has a noted recurring collaboration with scenario writer Masada, appearing in several games from the light franchise, including Paradise Lost, Dies irae, and Kajiri Kamui Kagura. His voice is sometimes mistaken for that of fellow voice actor Nobuo Tobita due to similarities in tone.
