Mount Dainichi (大日ヶ岳, Dainichi-ga-take) is a mountain located in the cities of Gujō and Takayama in Gifu Prefecture, Japan.

Taichō (泰澄, 682–April 20, 767) was the first person to climb Mount Dainichi in 717.

From the peak of the mountain, hikers can pray to nearby Mount Haku.

In pre-modern Japan, Mount Dainichi formed part of the border between Mino, Hida and Echizen provinces.

It was first part of the town of Shirotori, which was later merged into the city of Gujō.
