Megumi Mizusawa, born July 3, 1963 in Osaka Prefecture, is a Japanese manga artist known for her long-running career in shōjo manga, particularly during the late 1980s and 1990s. She made her professional debut at the age of sixteen with the short story Kokoro ni Sotto Sasayaite, published in the September 1979 issue of Shueisha's Ribon magazine. She later graduated from the prestigious Waseda University with a degree in education.

Mizusawa is best recognized as the original creator of the magical girl series Hime-chan no Ribbon, also known as Hime-chan's Ribbon. The manga was serialized in Ribon magazine from August 1990 to January 1994 and was subsequently compiled into ten volumes. The series proved to be a significant success and was adapted into a sixty-one episode anime television series produced by Studio Gallop, which aired on TV Tokyo from October 1992 to December 1993. A stage musical based on the property was also produced in December 1993. A sequel or reimagining of the original manga, titled Hime-chan no Ribon Colorful, was later serialized in Ribon from October 2009 to December 2010, but this version was written and illustrated by a different artist, Shiho Komiyuno.

Beyond her most famous work, Mizusawa has an extensive bibliography of manga titles published primarily by Shueisha. Her other notable series include Pony Tail Hakusho (five volumes), Sora Iro no Melody (five volumes), Chime (three volumes), Oshaberi na Jikanwari (two volumes), Naisho no Princess (four volumes), Toe Shoes (five volumes), and Kira Kira 100% (nine volumes). Her career also includes numerous short story collections such as Gogatsu no Ochakai, Kimagure na Yokan, and Nemuri-hime no Eve. In the early 2000s, she transitioned from Ribon, a magazine for younger girls, to Cookie, a Shueisha publication aimed at a more mature female audience.

Her artistic style, particularly in her early works, was influenced by fellow Ribon artists Ako Mutsu, Yumiko Tabuchi, and Hideko Tachikake. She is known for maintaining a simple, cute, and gentle aesthetic that appeals to young readers. Common themes in her work include everyday life, first love, and the personal growth of young female protagonists, often drawing on autobiographical elements as seen in Oshaberi na Jikanwari, which is based on her own experiences with first love.

Megumi Mizusawa is married to film director and screenwriter Katsuo Naruse and has two daughters. Her hobbies include classical ballet and playing the guitar. She remains a significant figure in shōjo manga history as one of the prominent artists during the golden age of Ribon magazine.
