WNRN-FM (91.9 FM) is a non-commercial, listener-supported radio station licensed to Charlottesville, Virginia, serving Central and Western Virginia. The station has a board of directors consisting of local community members and is incorporated as the non-profit Stu-Comm, Inc.

WNRN-FM has an adult album alternative (AAA) radio format. It is the only member of National Public Radio based in Charlottesville, and carries NPR's daily music program World Cafe, as well as locally produced specialty music shows on weekends.

WNRN-FM has a network of rebroadcasters and FM translators around Virginia, covering the Shenandoah Valley from Roanoke to Harrisonburg as well as Richmond, Williamsburg and Hampton Roads. It holds periodic fundraisers on the air to support the station and network. The main station has an effective radiated power (ERP) of 320 watts, with its transmitter at the Carter's Mountain antenna farm in Charlottesville.

In 1993, Mike Friend, a former operations manager at WTJU (owned and operated by the University of Virginia), incorporated Stu-Comm, Inc. "with the purpose of building a non-commercial FM radio station for the Charlottesville-Albemarle area." WNRN-FM took the call sign WANJ during the construction process. WNRN-FM was originally registered as an "educational nonprofit". It signed on the air as WNRN in September 1996; 28 years ago (1996-09).

In 2006, the station gained a direct commercial competitor in pop-oriented AAA station WCNR (106.1 FM), branded as "106.1 The Corner". Founder and then-general manager Mike Friend banned the word "corner" from his airwaves for a time after WCNR signed on.

In 2000, WNRN began expanding its service area outside of Charlottesville: first by renting airtime on WUDZ (now WNRS-FM), then the Sweet Briar College student radio station, followed by several purchases of translator stations in Lexington, Richmond, Harrisonburg and Lovingston in 2006 and 2007. Stu-Comm, Inc. purchased WNRS-FM outright in 2010, increasing its height and power in order to reach Lynchburg. Although the main signal from Carters Mountain nominally has good coverage in the lower elevations to the east, including Richmond, interference from co-channel WGTS in Washington, D.C. cuts down on reception in those areas.

Stu-Comm, Inc. took additional steps to improve its terrestrial signals in 2016, starting with the acquisition of WFTH (1590 AM) in Richmond, which enabled it to purchase and move in an additional FM translator under the Federal Communications Commission's (FCC) "AM revitalization" program. This new translator, W203CB on 88.5 FM from Midlothian, became WNRN's primary Richmond-area signal on February 2, 2018. W203CB replaced W276BZ (103.1 FM), which prompted listener complaints as it broadcast at only 10 watts and had difficulty covering the city.

Hanover County-based WHAN (1430 AM), with a transmitter and FM translator (W275BQ, 102.9 FM) located in Ashland and covering the northern suburbs of Richmond, filed an agreement donating its license and facilities to Stu-Comm, Inc. on July 31, 2020; this gave WNRN a third and fourth signal covering the city. The action came concurrently with the FCC repeal of a longstanding rule prohibiting co-owned AM stations with substantial signal overlap from simulcasting each other. WHAN came under Stu-Comm, Inc.'s control on October 14.

In 2022, Stu-Comm entered the Hampton Roads market with the purchase of WRJR (670 AM), which is licensed to Claremont in Surry County but has a signal powerful enough to cover the entire region during the day. WRJR's companion FM translator W273DZ (102.5 FM) is located in Hampton and at least marginally covers Williamsburg, Newport News, Norfolk, and Virginia Beach. WNRN programming commenced on June 3.

Stu-Comm purchased Staunton's WTON-FM (94.3 FM) and WTON (1240 AM) on September 25, 2023; the FM signal replaced the translators covering Staunton–Waynesboro and Harrisonburg and allows for full coverage of the lower Shenandoah Valley for the first time. The sale closed on December 4. The two translators were sold along with WTON the following April.

The station changed its call sign to WNRN-FM on January 2, 2024, with the WNRN call sign simultaneously moving to WFTH.

In the summer of 2024, Stu-Comm expanded WNRN's service area to Roanoke by purchasing WGMN (1240 AM) and its companion FM translator W258DN (99.5 FM). Programming began over the two stations on July 1.

WNRN is the only member of National Public Radio based in Charlottesville, though it is a member strictly to carry its music programs; full NPR news and talk service is provided to the city by repeaters of Roanoke-based WVTF and Harrisonburg-based WMRA. World Cafe airs at 6 p.m. on weekdays, and All Songs Considered and Alt.Latino air on Sunday mornings. Locally produced specialty shows heard on weekends include Bluegrass Sunday Morning, Fresh Roots, New Blues, Les Temps Perdu and Grateful Dead and Phriends. Outside of these shows, the station plays continuous adult album alternative music with live airstaff on duty from 6 a.m. to midnight daily.

The station made local headlines when Mike Friend was unexpectedly fired as manager by the board of directors in April 2011, although he was kept on as the station engineer. Friend left WNRN altogether in 2013 and founded Blue Ridge Free Media, the licensee of WXRK-LP (92.3 FM). The station's assistant general manager, Anne Williams, became acting general manager. Mark Keefe replaced Dave Benson as general manager and program director May 31, 2014.

As of June 2020, Ian Solla-Yates served as development director and Lauren Velardi as membership director. Desiré Moses was managing producer, host, and music writer. Bob Mosolgo was Morning Host. Amber Hoback is music director.

Longtime "Acoustic Sunrise" host Anne Williams worked her last on-air shift on February 15, 2019, after a two-decade run as a cornerstone of the station's schedule. Williams took a management position at Knoxville Americana station WDVX.
