Kamen Rider Den-O the Movie: I'm Born! (劇場版 仮面ライダー電王 俺、誕生！, Gekijōban Kamen Raidā Den'ō Ore, Tanjō!, Masked Rider Den-O the Movie: I'm Born!) is the theatrical tokusatsu superhero film adaptation of the Kamen Rider Den-O TV series directed by Takao Nagaishi and written by Yasuko Kobayashi. The movie takes place between episodes 27 and 28 of the series, featuring the DenLiner and its passengers travel as far back as the Edo period of Japan.

The film is produced by Ishimori Productions and Toei, the producers of all the previous television series and films under the Kamen Rider franchise. Following the tradition of all Heisei Kamen Rider movies, it is a double bill with 2007's Super Sentai movie, Juken Sentai Gekiranger: Nei-Nei! Hou-Hou! Hong Kong Decisive Battle, both of which premiered on August 4, 2007. The film's title is translated into English as both Masked Rider Den-O The Movie: I'm Born! and I'll be born! on the initial collector's pack DVD release.

During its first week at the theaters, the movie came in 4th place and was the highest selling Japanese production of the week.
