Fladnitz an der Teichalm is a municipality with 1804 inhabitants (as of 1 January 2016) in Styria. As part of the municipal structural reform in Styria in 2015, it was merged with the communities Tulwitz and Tyrnau to the new community Fladnitz an der Teichalm. The basis for this is a joint application of these communities. The boundaries of the Graz-Umgebung and Weiz districts have been changed so that the new municipality is located entirely in the district of Weiz.
