No Bra (Japanese: のーぶら, Hepburn: Nō Bura) is a Japanese teenage boy's romance manga written and illustrated by Kenjiro Kawatsu that was serialized in Weekly Shōnen Champion from 2002 to 2004.

No Bra tells the story of Masato Kataoka, a somewhat dimwitted high school student, whose childhood friend Yuki Nomura moves in with him one day.

The story initially revolves around Masato's relationship with Yuki and his slowly disintegrating reluctance to develop romantic feelings for her.

It later began to focus heavily on other characters' acceptance of Yuki's existence as a trans female, though not without numerous instances in which they call her a "cross-dresser".

Yuki promptly becomes one of the most popular girls in the class, alongside Kaoru Oozora, whom Masato nurses a crush on.
