WVBR-FM (93.5 FM) is a commercial radio station licensed to Ithaca, New York, United States. Owned by the Cornell Media Guild, a non-profit organization, it is student-operated and volunteer-run, with an alternative rock format on weekdays with talk and variety programs on weekends. The station is supported by advertisements but it also seeks donations on the air and on its website. The studios and offices are on East Buffalo Street in the Collegetown district of Ithaca. WVBR-FM's transmitter is sited on Hungerford Hill in East Ithaca.

WVBR is a commercial radio station that it is owned, operated and managed by Cornell University students who comprise the non-profit Cornell Media Guild, Inc. (CMG). The station is ad-supported and independent of the university. WVBR and the Guild are a training ground for students interested in media and broadcasting, as well as a serious commercial competitor in the Ithaca radio market.

There are also community members, of all ages, who are involved with the station. Student and volunteer staff members are, for the most part, unpaid. Some staff earn commissions on time sales or are paid a stipend to help operate the station during the summer and other times when Cornell classes are not in session.

WVBR is very involved in the city of Ithaca and Tompkins County. The station features a "Community Calendar" segment twice daily, where non-profit organizations can send bulletins of their events to be read over the air during the morning and afternoon. WVBR also does remote broadcasts from locations including the Ithaca Farmer's Market, Ithaca-area concerts, and local businesses around town. WVBR also sponsors local charitable and cultural events.

WVBR purchased, remodeled and relocated to a new studio in Collegetown, located at 604 E. Buffalo Street. A ribbon-cutting event was held on March 15, 2014, where the new building was named the Olbermann-Corneliess Studios, after Keith Olbermann's father, Ted, and his close friend and alumnus, Glenn Corneliess. Prior to 2016, WVBR had a translator on 105.5 FM.

WVBR's history goes back to 1935 when the Cornell Radio Guild was formed (incorporated in 1941) as a Cornell student organization that produced radio programs that aired on WESG, the forerunner of WHCU 870 AM. In the early 1940s, the Guild started a network of its own low power AM "carrier-current" transmitters in the dormitories. For a time, the signal of those transmitters was powerful enough, and connected to enough of the regional power grid, that the signal was widely heard beyond campus.

A hoax broadcast in the early 1950s resulted in the FCC ordering the Guild to take steps to restrict the reach of the signal to the immediate campus area. At this point, CMG began a search for a suitable frequency on either AM or the newly emerging FM to conduct a genuine regional broadcast service. That search was successful in 1957, when a construction permit was issued by the FCC to allow CMG to build and operate an FM station, first at 101.7 MHz. Before broadcasts began, the specified operating frequency was changed to 93.5 MHz, and WVBR-FM has broadcast on that frequency ever since.

The FCC-licensed FM station signed on the air in June 1958. The WVBR call letters had already been in use for years on the Guild's AM "carrier-current" broadcasts, which could be received only on campus. The call sign originally stood for "Voice of the Big Red", referring to the Cornell Big Red athletic teams. However, the station de-emphasized that connection over the years as it carved out an identity independent of the university. Cornell's sports broadcasts were generally carried by WHCU 870 AM, a commercial station that Cornell owned for many years. But this has changed to a degree in recent years as WVBR has become the originating station for sponsored broadcasts of some major Cornell sports, including football, basketball and hockey.
