Bad Mitterndorf ({{IPA|de|baːt ˈmiteʁnˌdɔʁf|lang}}) is a town in Salzkammergut in the Austrian state of Styria.

Situated between Salzburg and Graz, it is a popular winter sports resort and also as a location for walking and cycling in the summer. Bad Mitterndorf is the site of two health spas with thermal baths, an outdoor swimming pool and other health amenities, cafés and leisure areas. The town hosts a children's club during the holidays. Bad Mitterndorf is also the location of one of the world's five ski flying hills, Kulm. The town is well placed for excursions to Hallstatt, Altaussee and its May narcissus festival, Bad Ischl and the Kaiservilla, and to Salzburg, 95 km away.
