Shiwaguchi Station (志和口駅, Shiwaguchi-eki) is a JR West Geibi Line station located in Ibara, Shiraki-chō, Asakita-ku, Hiroshima, Hiroshima Prefecture, Japan.

The "Shiwa" in the name derives from the nearby Shiwa-chō, Higashihiroshima, despite there being no shuttle bus or other connection between the two locations.

This station should not be confused with other stations of similar-sounding name on the Geibi Line: Shimowachi, Shiomachi, and Shiwachi.

Shiwaguchi Station features one raised island platform, capable of handling two lines simultaneously.

Two convenience stores are located directly across from the station.
