Tachikawa Station (立川駅, Tachikawa-eki) is a junction passenger railway station located in the city of Tachikawa, Tokyo, Japan, operated by the East Japan Railway Company (JR East).

The Lumine department store occupies the upper floors of the station building.

The Kōbu Railway, which later became the Chūō Main Line, opened the station on April 11, 1889.
