Masayuki Kojima (小島 正幸, Kojima Masayuki) is a Japanese animator, storyboard artist, and director, best known for directing the acclaimed anime series Monster and Made in Abyss. He was born on March 11, 1961, in Yamanashi, Yamanashi, Japan.

Kojima first got his start in the animation business in the 1980s, where he worked primarily project-to-project for a number of different companies, including Knack Productions and Tatsunoko Production. During this time, his involvement was in television products mostly as an episode director. After joining Madhouse in the 1990s, he took part in dozens of productions as an animator, as well as helming several TV series, two films, a theatrical short, and a TV special. He has since left the studio and joined Kinema Citrus in 2011.

Since coming to work for Madhouse, Kojima has been primarily a drama director, and one who specializes in lengthy series. He has directed two adaptations of Naoki Urasawa's manga, Master Keaton and Monster, both of which have received critical acclaim. His first full-length theatrical film, Piano no Mori, was released in Japan on July 21, 2007.
