WQQO (105.5 FM) is a commercial radio station licensed to Sylvania, Ohio, carrying a hot adult contemporary format known as "Q105".

Owned by Cumulus Media, the station serves the Toledo metropolitan area and much of surrounding Northwest Ohio.

[2] The 105.5 MHz spot on the radio dial in the Toledo area began in November 1968 as WGLN, located in a cornfield in western Lucas County, the remote studio-transmitter location was the home of the "Jones Boys", a concept introduced in Toledo by station manager and native Toledoan Michael Drew Shaw.

In response to the format change, a citizens' group known as the Citizens' Committee to Keep Progressive Rock filed an objection with the FCC on the basis that Toledo already had several other middle-of-the-road/easy listening-type format stations and did not need another; the FCC rejected the appeal, and the committee continued to appeal the rejection until the Reams family changed WCWA-FM (104.7) to WIOT in December 1972, after which the objection was withdrawn.

[3] At this time, 105.5 FM was still located in its tiny studio in the rural cornfield setting at its transmitter site in Berkey, Ohio.

In April 2007, Star 105.5 became Toledo's home for Delilah's syndicated love-songs program, which competes with the John Tesh show on Clear Channel's WRVF.

[9] On September 1, 2023, ahead of the Labor Day weekend, WQQO shifted to a hot adult contemporary format leaning towards 1990s and 2000s music, though retaining the "Q" brand and a small amount of more current and recurrents, mirroring similar format shifts at Top 40 outlets across the country in the previous year.

[10] WQQO airs a sports talk format on its HD2 subchannel, branded as "ESPN 100.7 The Ticket" (simulcast on translator W264AK 100.7 FM).
