Svartisen is a collective term for two glaciers located in northern Norway. The system consists of two separate glaciers,

• Vestre (western) Svartisen (221 km²), which is the second largest glacier on the Norwegian mainland (there are larger glaciers on Svalbard) after Jostedalsbreen
• Østre (eastern) Svartisen (148 km²), which is the country's fourth largest.

There are also a number of minor glaciers in the area, such as Glombreen in the northern part of Meløy, and Simlebreen in Beiarn. One of the outlet glaciers of Svartisen, Engabreen ends at the lowest point of any glacier on the European mainland, at 20 meters above sea level (in 2007). The Norwegian Water Resources and Energy Directorate has monitored the glacier mass balance of the glacier since 1970 and operates a sub-glacial laboratory beneath Engabreen.
