Kamen Rider World (仮面ライダーワールド, Kamen Raidā Wārudo) is a short tokusatsu superhero 3-D film produced by Toei Company based on the Kamen Rider Series that premiered on August 6, 1994 and was shown in amusement parks and special events nationwide in Japan. It was shown as a triple feature alongside Super Sentai World and Toei Hero Daishugō (a crossover between Tokusou Robo Janperson and Blue Swat which also used footage from Super Sentai World).

The film is included as a bonus feature in the Region 2 DVD release of Kamen Rider J by Bandai Visual and Toei Video. The DVD version lacks the 3D effects from the theatrical release. A Blu-ray 3D release is featured in a bonus disc included in the Kamen Rider: The Movie 1972-1988 Blu-ray Box set, released on May 11, 2011, which retained the 3D effects from the theatrical version.

Media Blasters licensed the short along with Kamen Rider ZO, Kamen Rider J and Shin Kamen Rider: Prologue. It will be released in North America in the summer of 2024.
