Ho-Seong Kim was a South Korean voice actor, born September 7, 1969. He joined the Munhwa Broadcasting Corporation voice acting division in 1996.

In the realm of anime, his work was as a voice actor for Korean-language dubs. Among his most recognized roles is Mototsugu Inukai in the series Corrector Yui. In the original Japanese version, this character is voiced by Mugihito, while Kim Ho-Seong provided the voice for the character in the Korean broadcast. He also voiced the character Jidan Nickard in the series Mobile Suit Gundam: The 08th MS Team, a role originally performed in Japanese by Ichirō Nagai. Despite being referenced in the prompt, information could not be verified for the role of Herman Preminger in the series Ashita no Nadja; available records list a different actor for that character's Japanese voice, with no mention of a Korean dub counterpart.

Beyond specific anime titles, his broader voice acting portfolio included dubbing for international television series. He was cast in the Korean television edition of CSI: Crime Scene Investigation as the voice of Greg Sanders, a role originally played by Eric Szmanda. His work also included the Korean edition of Smallville and the Korean TV edition of Fullmetal Alchemist. Ho-Seong Kim passed away on May 18, 2021.
