|This article is about a/an organization in Kamen Rider Fourze.|
- "The Kamen Rider Club. A club that exists to protect this school from monsters."
- ―Gentaro's description to Kengo about the club.[src]
The Kamen Rider Club (仮面ライダー部, Kamen Raidā Bu) is a school club at Amanogawa High School (AGHS) that was founded by Gentaro Kisaragi, with Yuki Jojima as co-founder, after being inspired by the urban legends of the previous Kamen Riders.
The club's main purpose is to assist Gentaro as Kamen Rider Fourze in his fight against the Zodiarts.
All members of the club are sworn to secrecy about the club, and 'membership' officially begins when the member and Gentaro shake hands. The only exceptions are Ryuusei (who personally asks and wasn't allowed until Gentaro saw his 'true personality'), and Ohsugi, who announced that he would be the club's advisor.
In Movie War Ultimatum, the founding members were now alumni and have attained their respective dreams. Gentaro returned to AGHS as the club's new faculty advisor.
The club's headquarters is within the Rabbit Hatch, accessed by a Cosmic Energy powered portal in a locker in an abandoned part of the campus. All members are invited to go onto the moon's surface as part of an initiation to the club.
After the series finale, the club's activities are now held elsewhere as the Rabbit Hatch was destroyed by Sagittarius.
In Movie War Ultimatum, the club gained a new clubroom similar to their old locker's storage room.
The following are the founding members of the club. They were the ones who fought to protect their school against the Horoscopes and their Zodiarts.
