Sølen (also called Rendalssølen, Søln, and Rendalssøln) is a mountain in Rendalen Municipality in Innlandet county, Norway.

The mountain lies about 25 kilometres (16 mi) east of the village of Bergset.

An old pilgrimage route from Sweden via Trysil to Nidaros Cathedral passes through the southern gorge.

The Sølen landscape conservation area was established in 2011 and it includes both the mountain massif and parts of the neighboring lake Sølensjøen.

[2] The name is maybe derived from the Old Norse word sǫlr which means 'sallow' or 'wan' referring to its color.
