The Avisio is an 89.4-kilometre-long (55.6 mi) Italian stream (a torrente), a left tributary of the Adige, whose course is in Trentino.
It rises from Marmolada and runs through the Fascia Valley, the Fiemme Valley and the Cembra Valley before joining the Adige in the town of Lavis, a small town 8 kilometres (5 mi) north of Trento.
