H.D. Quinn is the professional alias used by American voice actor, puppeteer, and performer Tyler Bunch. He has built an extensive career in children's television and animation, lending his voice to numerous projects since the 1990s. His work is particularly prominent in English-language dubs of anime and animated series.

Quinn is perhaps best known for his extensive contributions to the Pokémon anime franchise. He has voiced several significant characters across multiple series and specials. Notably, he is the voice of the villainous Lysandre, the leader of Team Flare, a role he performed in all four of the Pokémon: Mega Evolution specials, which are directly cited as Pokémon: Mega Evolution Special I, II, III, and IV. He also provided the voice for Ash's Hawlucha, a fan-favorite Pokémon, throughout the Pokémon the Series: XY&Z era, including in the special Pikachu to Pokémon Ongakutai. Another of his credits in the franchise is the character Oscar, the grandfather of a young girl named Anna, in the special Mewtwo ~Kakusei e no Prologue~. His Pokémon voice work continued into subsequent series, such as Pokémon the Series: Sun & Moon, where he voiced characters like Viren and Professor Kukui's Incineroar.

Beyond Pokémon, Quinn's work as H.D. Quinn encompasses a wide range of anime and animated productions. He voiced the character Gobson in the series The Snack World. His other anime credits include roles in the English dubs of Your Name, where he played Teshigawara's father, and Lu over the Wall, as the Homeroom Teacher. He has also been heard in series such as Yu-Gi-Oh! VRAINS, 44 Cats, and Regal Academy. In addition to anime, his voice can be found in numerous video games, most recognizably as the English voice of the Pokémon Incineroar in Super Smash Bros. Ultimate, a role for which he is credited as H.D. Quinn.
