The Gudenus cave (German: Gudenushöhle) is an archaeological site near the city of Krems in north-eastern Austria.

It is noted for its fossils and remains of Palaeolithic human settlers.

The Gudenus cavern is situated 20 km (12 mi) northwest of the city of Krems, in the valley of the Little Krems, not far from Willendorf, in Lower Austria.
