WBRU is an internet radio station based in Providence, Rhode Island. The station is owned and operated by Brown Broadcasting Service, an independent non-profit organization, and is primarily staffed by students from Brown University.

Formerly an FM modern rock radio station that broadcast at 95.5 FM in the Rhode Island area, WBRU currently broadcasts two online stations with different genres on each: indie and alternative on WBRU and an urban contemporary format on WBRU360, named after its long-time Sunday program, The 360° Experience in Sound. Since January 2018, WBRU's urban contemporary programming has been rebroadcast on Providence low-power FM station 101.1 FM, which is owned by another Brown University-affiliated group and has the call sign WBRU-LP.

WBRU has its origins in The Brown Network, which was founded in 1936 as one of the earliest amateur college radio broadcasters. By the time that the Brown Broadcasting Service organization was founded in 1962, radio broadcasting on the Brown University campus had turned from a hobbyist activity to a more serious enterprise. The organization purchased a commercial FM license in 1965 and aired its first broadcast on WBRU-FM on February 21, 1966. The station aired with a progressive rock format in the 1960s and 1970s, added new wave music into its playlist in the early 1980s, and switched to its current modern rock format in 1988. From 1966 to 2017, WBRU aired on the 95.5 FM frequency in the Providence market. In August 2017, Brown Broadcasting Service sold the 95.5 license to Educational Media Foundation and WBRU was replaced on that frequency by WLVO, a Christian adult contemporary station, at midnight on September 1, 2017. Although its primary alternative rock programming is no longer available on an over-the-air radio station, WBRU itself continues to be operated by BBS, and offers both its alternative rock and urban contemporary programming as an online-only programming provider.

WBRU traces its origin to "The Brown Network", a low-power carrier current station that broadcast at 570 kHz on the AM band, and whose signal was limited to the Brown campus. (At this time, the two National Broadcasting Company (NBC) radio networks were known as the "Red Network" and the "Blue Network".) This first-ever carrier current station was established 1936 by George Abraham and David W. Borst. Abraham had originally installed an intercom system between his and Borst's dormitory rooms. The intercom links were first expanded to additional locations, and then replaced by distributed low-powered radio transmitters, which fed their signals into various buildings' electrical wires, allowing nearby radio receivers to receive the transmissions. Abraham originally conceived of the idea as a way to share his record collection and serve as a personal disk jockey for his friends. By the next year, he had installed wires through the trees on campus in order to connect to a number of buildings, assigning students in individual dormitories to act as "section managers" who would receive the signal and retransmit it throughout the rest of their building. After being recognized as an extra-curricular activity, The Brown Network was assigned a studio and control room located in the Faunce House student union building.

The New England Hurricane of 1938 destroyed most of the distribution wires, and Borst and Abraham were forced to move the wires into the steam tunnels beneath the campus. On November 3, 1939, David Sarnoff, the president of the Radio Corporation of America (whose son attended Brown) made a broadcast over The Brown Network. On February 17–18, 1940 an organizing convention for the Intercollegiate Broadcasting System (IBS) was held at Brown, attended by representatives from twelve colleges with existing or proposed carrier current stations. Abraham was elected the IBS Chairman, and Borst the Technical Manager. IBS's role was defined as a medium for the exchange of ideas and programs, in addition to working to attract national advertising contracts for the member stations. The first IBS intercollegiate broadcasts began on May 9, 1940, with a five-part series that was carried by stations located throughout New England at Brown, Harvard, Williams, and Wesleyan universities, in addition to the Universities of Connecticut and Rhode Island.

In 1945, student journalists began to use the WBRU call letters on air, which had been coined by undergraduate Stephen Plimpton.

In 1962, the Brown Broadcasting Service (BBS) was established as a separate entity from the University and in 1965, the BBS purchased a commercial FM license (WPFM) from a company that was "bankrupt". WPFM was assigned from Golden Gate Corporation to BBS on April 9, 1965 for consideration of $30,000. BBS was then split into two stations: "WBRU-AM" and WBRU (FM). WBRU-AM, whose callsign was not FCC-assigned, continued to broadcast locally as a carrier current station (distributed through Brown's electrical system) and operated as the training station for WBRU, the FM station.

Brown Broadcasting Service began broadcasting over WBRU at the 95.5 frequency on February 21, 1966; The first program to be transmitted from the new station was a panel show which discussed the Peace Corps.
