Kleinlobming is a village and former municipality in the Bezirk Murtal, in the Austrian state of Styria. It lies in the Lobming valley area of the Murtal district, in the region of Upper Styria.
Until the 2015 Styria municipal structural reform, Kleinlobming was an independent municipality. Under that reform, which reduced the number of municipalities in Styria through mergers, it was incorporated into the municipality of Großlobming. Kleinlobming has since been a part of Großlobming rather than a separate administrative unit.
The settlement is therefore one of several former Styrian municipalities whose independent status ended in 2015, and it is now counted within the boundaries and administration of Großlobming in the Murtal district.
