Tiveden is a Swedish forest famous for its scenery and notorious throughout history for its wilderness and dangers. It was a notorious hiding place for outlaws. Tiveden National Park is a comparatively small part of the forest (13.5 km²), situated within the municipalities of Karlsborg and Laxå. It was established in 1983.

It is famous for its small lakes with red waterlilies. When they were discovered they provided the European varieties of red waterlilies that are in cultivation.

The name is very old and disputed. -Ved is cognate to English Wood and the first part of its name, Ti-, either means "god" or refers to the god Tyr. Tiveden separates Nericia from Westrogothia, and was formerly a frontier between the Geats and the Swedes.
