The Reither Spitze is a mountain in the Karwendel in the Austrian federal state of Tyrol that, thanks to its location at the southwestern end of the Erlspitze Group, is particularly well known for its great views of the surrounding area from its summit.

Its name is derived the village of Reith bei Seefeld, which lies at its southwestern foot.

The summit of the Reither Spitze may be reached in a 20-minute climb from the Nördlinger Hut to the south.

[1] The Nördlinger Hut is an hour's walk from the top station of the cable car on the Härmelekopf; from the Härmelekopf one can also ascend the Reither Spitze directly via the Reither Joch (sure-footedness required).

From the Seefelder Spitze, the Reither Spitze may be reached on an easy path (sure-footedness required) or directly along the connecting arête, a routed graded at UIAA level III difficulty.
