WLBL-FM (91.9 MHz) is a radio station licensed to Wausau, Wisconsin.

The station is part of Wisconsin Public Radio (WPR), and airs WPR's "Ideas Network", consisting of news and talk programming.

WLBL-FM also broadcasts local news and programming from studios in the Center for Civic Engagement at the University of Wisconsin-Marathon County in Wausau.

In a share-time arrangement, WLBL shares 91.9 with WXPW, a satellite of WXPR in Rhinelander.

Because of this, an HD Radio subchannel of the full Ideas Network schedule is heard on the third digital subchannel of WHRM-FM (90.9), a sister station to WLBL which carries WPR's NPR News and Classical service.
