The Spannagel Cave () is a show cave near Hintertux, in the Zillertal Alps in the Austrian state of Tyrol. Currently about 10 kilometres of cave have been discovered; guided tours enable access to 500 metres of the cave. Its entrance lies below the Spannagelhaus (2531 m), a mountain hut formerly run by the Austrian Tourist Club (ÖTK). The cave and the hut are named after Dr. Rudolf Spannagel, who was the president of the ÖTK from 1902 to 1904.
