Yumiko Kobayashi

is a freelance Japanese voice actress from Chiba Prefecture. She was formerly affiliated with Arts Vision until August 2007. She made her voice acting debut as Mita in ''Kirara'' while still in college in 1998, and her first lead role was as Kento Yūki in ''Dennō Bōkenki Webdiver'' in 2001. She is still good friends with Natsuko Kuwatani, Hisayo Mochizuki, and Nana Mizuki, members of the former voice acting unit Prits; all four voiced characters in ''Sister Princess''.

In an interview in 2019, Kobayashi said that shortly after her debut, while researching how to play a boy who can be dubbed, she came to believe that there was no better way to act than as a child actor, but she was struck by Akiko Yajima's performance as Kevin, the main character in ''Home Alone'', and has since made it her goal. Beginning with the July 6, 2018 episode, she took over the role of Shinnosuke Nohara in ''Crayon Shin-chan'' from Yajima, who had played the role since the show began airing on April 13, 1992.
