Sylan

, , or is a mountain range on the border between Norway and Sweden. The mountain range lies in Tydal Municipality in Trøndelag county (Norway) and in Åre Municipality in Jämtland county (Sweden).

The central part of the range includes a large mountain ridge that starts at the tall mountain Lillsylen in the north then heading south to the tall Storsylen (the highest point in the mountain range), and further south to the tall mountain Storsola. Traversing the ridge is a popular trip for experienced hikers, and is easiest from the south to the north, due to a scrambling point about south of the Storsylen summit.
