Bletoppen or Store Ble is a mountain in Tinn Municipality in Telemark county, Norway.

The 1,340-metre (4,400 ft) tall mountain is located about 10 kilometres (6.2 mi) southeast of the village of Hovin and about 30 kilometres (19 mi) north of the town of Notodden.

[2][1] From the summit, there is a view of Jonsknuten and Skrimfjella in the southeast, Lifjell in the southwest, Gaustatoppen in the west, and Hardangervidda in the northwest.

The summit is most easily reached by following a marked trail from the parking lot at Nordstul, a 3 to 4 hour hike in the summer.

Numerous shorter paths start at the road to Fosskard and go up the steep western side of Blefjell.
