Innerdalen is a valley in Sunndal, Møre og Romsdal, Norway and is also Norway's first nature reserve.The valley and nature reserve goes from Ålvundeid by highway 70 in the east, and approximately 25 km to the west to Innerdalsporten, and lies within the mountain range Trollheimen.

The valley is known for its mountains and is regularly visited by mountain climbers, for example the mountains Store Trolla (1,850 m, highest in Trollheimen), Skarfjellet (1,790 m), and Innerdalstårnet (1,452 m).Norsk Tindeklub (Norwegian Mountaineering Association) released in 2001 a mountain guide for Innerdalen (in Norwegian) and also has a private cabin, Giklingdalshytta beneath Innerdalstårnet.

For glacier hiking, there is a glacier on top of Kongskrona called Vinnufonna.

The Norwegian Mountain Touring Association has two cabins in the valley, Innerdalshytta (originally built 1889) and Renndølsetra.
