Yashio Station (八潮駅, Yashio-eki) is a passenger railway station located in the city of Yashio, Saitama, Japan, operated by the Metropolitan Intercity Railway Company. Its station number is TX08.

Yashio Station is served by the Tsukuba Express, and is located 15.6 km (9.7 mi) from the terminus of the line at Akihabara.

The station consists of two elevated island platforms serving four tracks, with the station building underneath. Trains generally stop at the outer platforms (1 and 4), but when a faster train stops or passes through the station, the inner platforms are used to hold the slower trains. Yashio is one of three stations on the Tsukuba Express (Nagareyama-ōtakanomori and Moriya) where parallel tracks allow for trains traveling in the same direction to pass each other. Some trains terminate at Yashio Station, especially during the morning commuter rush between Yashio and the Akihabara terminal. Immediately north of the station are four tracks that can hold trains as they are taken out of service, or put into service.
