Thuringian Forest Nature Park (German: Naturpark Thüringer Wald) is one of two nature parks in the state of Thuringia, Germany.

Founded in 1990, and expanded in 2018, the nature park now covers and area of more than 2,200 km2 (850 sq mi).

The highest mountains in the park are the Großer Beerberg (982 m above sea level (NN)) and the Schneekopf (978 m above sea level (NN)).

The nature park is an expansion of an older protection; the "UNESCO Biosphere Reserve Thuringian Forest" established in 1979 as the first UNESCO biosphere reserve in Germany.

The biosphere protection is located in the Thuringian-Franconian low mountains, and after expansions in 1990 and 2018 it now covers an area of 337 km².
