This article is about a/an series of movies in the Kamen Rider Series.

The Movie War Series (MOVIE大戦シリーズ, Mūbī Taisen Shirīzu^?) is a recent group of movies that serve as crossovers with two immediate Series installments within the Kamen Rider franchise, having started with W and Decade, the former being the first show of the Neo-Heisei era. They are shown around mid-December. Every movie so far has featured all the leading Neo-Heisei riders at the time, thus, Kamen Rider Double has appeared in all of them.

It can be considered the Kamen Rider Series' equivalent to the VS. movies of Super Sentai, which had celebrated its 15th anniversary before the start of the Movie War Series.

Similar to how Kamen Rider Decade: All Riders vs. Dai-Shocker started the tradition of Summer Movies featuring a cameo appearance of the lead Kamen Rider of the up-coming new series, the Movie War films feature a cameo appearance of the Secondary Rider of the current series.
