The Gosau Group (German: Gosau-Gruppe) is a geological stratigraphic group in Austria, Germany and western Slovakia whose strata date back to the Late Cretaceous to Eocene.

[1][2] It is exposed in numerous sporadic isolated basins within the Northern Calcareous Alps.

The formations within each subunit vary significantly between basins.

The sequence is largely marine, but the Grünbach Formation represents a terrestrial deposit.

Many of the units of the group are fossiliferous, typically providing marine fossils such as ammonites, though terrestrial remains including those of dinosaurs are known from the Grünbach Formation and Schönleiten Formation.
