Yōko Maki, born Yōko Fuke on July 11, 1981, is a Japanese former manga artist known for creating several notable shōjo manga series. She made her professional debut in 1999 with the short story Love Service! in the magazine Ribon Original, which is published by Shueisha. Over the course of her career, which spanned two decades, Maki established herself as a consistent contributor to the shōjo genre, with her work regularly appearing in Ribon magazine.

Maki is the original creator of the manga series Aishiteruze Baby, which was serialized in Ribon from April 2002 to January 2005 and collected into seven volumes. The story follows a teenage boy who suddenly becomes the primary caretaker for his five-year-old cousin. The series was adapted into a twenty-six episode anime television series that aired in 2004. Another of her major works is The Romantica Clock, which was serialized in Ribon from August 2012 to June 2016 and compiled into ten volumes. This series was also adapted into an anime television series that aired as a segment on TV Tokyo's program Oha Star in February 2014.

Beyond these two well-known titles, Maki created a substantial body of work. Her other manga series include Yamamoto Zenjirou to Moushimasu in five volumes, Star Blacks in two volumes, Taranta Ranta in two volumes, and Atashi wa Bambi in three volumes. She also authored several short story collections, such as 14R, Kareki ni Koi o Sakasemasu, and Sora Sora. In addition to her solo work, she collaborated with her sister, Mochida Aki, on the manga Zen Zen. Her final series, Kirameki no Lion Boy, ran from 2016 to 2019. On July 3, 2019, Maki announced her retirement from the manga industry, concluding a career that began twenty years earlier. Her artistic identity is rooted in the shōjo romance genre, often exploring themes of young love and personal relationships, and her work has been published internationally by companies such as Viz Media in North America and Tokyopop in Germany.
