Pistorf is a former municipality in the district of Leibnitz, in the Austrian state of Styria. It lies in the southern part of Styria, a region known for its rolling hills, vineyards, and wine production.
Since the 2015 Styria municipal structural reform, Pistorf is no longer an independent municipality and has been part of the municipality of Gleinstätten. The reform merged a number of small municipalities across Styria into larger administrative units.
