Itsasbegi is a railway station in Busturia, Basque Country, Spain.

It is owned by Euskal Trenbide Sarea and operated by Euskotren.

The station opened as the northern terminus of the Gernika-Pedernales extension of the Amorebieta-Gernika line, on 15 March 1893.

Between 1948 and 1949, due to the extension of the line towards Bermeo, the station was completely renovated.
