The Chūō Line (Rapid) (中央線快速, Chūō-sen kaisoku) is the name given to rapid services on the eastern section of the Chūō Main Line operated by the East Japan Railway Company (JR East) between Tokyo and Takao stations.

Operation of electric multiple unit (EMU) trains on the Chūō Main Line began in 1904.

By 1930, the EMU service had reached Tokyo to the east and Asakawa (now Takao) to the west.

On these additional tracks, express trains (急行電車, kyūkō densha), which skipped all stations except Yotsuya and Shinjuku, were introduced the same year.

Work will be involved in lengthening station platforms and depot facilities to handle the longer trains.

The Chūō Line (Rapid) uses the two express tracks on the four-track section between Ochanomizu and Mitaka stations.
