Gråkallen is a mountain in the Bymarka area of Trondheim Municipality in Trøndelag county, Norway. The 552-metre (1,811 ft) tall mountain is located in the Byåsen part of the city of Trondheim.
The summit is covered by an abandoned fenced military installation. Below the summit (on the col to the right of the summit above the lake) there is a ski station accessible by bus from Trondheim. In the summer, the ski runs through the pine forests allow hiking and mountain biking back to the city below.
