Söchau is a municipality in the district of Hartberg-Fürstenfeld, in the Austrian state of Styria. It lies in the eastern part of the country, within the broader Hartberg-Fürstenfeld administrative area.
As a municipality, Söchau is a small local administrative unit rather than a large urban centre, and it forms part of the rural and semi-rural landscape typical of this part of Styria. The district of Hartberg-Fürstenfeld was formed through a regional administrative merger and serves as the local government framework for Söchau and its neighbouring communities.
Detailed information about the municipality's history, population, landmarks, and economy is limited in widely available sources, so only its administrative identity and location can be stated with confidence.
