The Grüne Tanne (German: Green Fir) is a historical Gasthaus by the Camsdorf Bridge in Jena, Thuringia, Germany.

The age of the building cannot be definitively determined owing to many renovations over the years, though the vaults of the cellar suggest an initial construction in the Gothic period (12th to 14th century).

The inn has borne the name "Grüne Tanne" since 1751, at which time it belonged to the village of Camsdorf east of Jena.

During his residence in Jena from 1817 to 1818, Johann Wolfgang von Goethe stayed on the top floor of the Grüne Tanne.

In 1993, the Grüne Tanne was renovated and began again to be used as a headquarters (Korporationshaus) for the Arminia Burschenschaft on the Burgkeller student society.
