This is a list of characters from the manga and anime series Ouran High School Host Club by Hatori Bisco. The series is about Haruhi Fujioka, a scholarship student at exclusive Ouran High School, who is forced to join the school's host club. The cast has been praised as comedic creations that play off bishōnen stereotypes that are also well-rounded.

Kyouya Ootori, age 17, is a second-year student at Ouran High School and the cunning and sly vice-president of the Host Club. Kyoya is best friends with Tamaki, despite their completely different demeanors. Tamaki tends to call him "Mom", or "Mother", in reference to Tamaki calling himself "Daddy". Kyoya is secretive and intelligent, being able to calculate any benefits that would come out of the Host Club's misadventures.
Although he doesn't put an act for the women, he is considered the "cool type."

The romanizations in the English-language editions of the manga published by VIZ Media and Chuang Yi differ from the English romanizations used on Nippon Television's Japanese-language website.
