The Navizence is a 23-kilometer-long Swiss river located in the Anniviers Valley, in the canton of Valais. It is a left-bank tributary of the Rhône River, joining it at Chippis.
The river originates from the Zinal Glacier and flows northward and then north-northwest. It passes through several streams, particularly from Vissoie, where its bed lies at the bottom of a crevasse. Its main tributary is the Gougra.
The water from the Navizence is utilized by multiple hydroelectric plants and can be pumped to the Moiry Dam via a system of galleries. The Navizence has encountered major floods in 1834 and 2018, resulting in extensive destruction in the Anniviers Valley and Chippis. The river is home to various benthic macroinvertebrates and brown trout.
