Princess Princess (Japanese: プリンセス・プリンセス, Hepburn: Purinsesu Purinsesu) is the title of a fictional series written and illustrated by Japanese author Mikiyo Tsuda about the lives of three high school boys and the school they attend.

Finally, a visual novel video game for the PlayStation 2 based on the series was released on October 26, 2006, in Japan.

The main protagonist, Toru Kouno, has just transferred to a new all-boys school, Fujimori, after living with his uncle for a time.

He is one such boy chosen to be one of the Hime (姫) or "Princesses", which is a tradition at the school in order to break up the monotony of life surrounded by nothing but males.

Students (based on certain qualifications) are selected to be Princesses and are made to dress up as girls and attend school functions like this.

Toru is convinced into becoming a Princess soon after entering the school though once he accepted the job, he found it to be much more enjoyable than he thought.

The school rules require the photography club to share profits with whoever serves as model for the photos they sell, and the photographs of the Princesses are the most sought-after.

The drama also excludes Mikoto's girlfriend, Megumi, and like the anime series features shōnen-ai overtones that are less present in the original manga.
