Storsjøen is a lake in the Odalen valley in Innlandet county, Norway. The lake straddles the municipal boundary between Sør-Odal Municipality and Nord-Odal Municipality. The lake lies just south of the village of Sand (in Nord-Odal Municipality) and just north of the village of Skarnes (in Sør-Odal Municipality).
The lake flows out into the Oppstadåa river which flows about to the south into the large Glomma river. When the river Glomma reaches high water levels, the river begins to flow into the lake Storsjøen. This phenomenon has given rise to the very special delta area at the southern end of the lake. This delta area has been protected as the Seimsjøen nature reserve.
The sea is rich in fish and an important stopover for waders and swimming birds. The lake is a popular tourist destination for many tourists.
