WGCI-FM (107.5 MHz) is an urban contemporary radio station that is licensed to Chicago, Illinois, serving the Chicago metropolitan area and Northwest Indiana. It is owned and operated by iHeartMedia (formerly known as Clear Channel Communications until September 2014).

WGCI broadcasts with 3,700 watts (3.7 kilowatts) from atop the Willis Tower in Downtown Chicago, and has studios located in the Illinois Center complex on Michigan Avenue. Like many Clear Channel-owned urban radio stations, it uses the slogan "Chicago's #1 For Hip Hop and R&B".

In 2005, WGCI began broadcasting in IBOC digital radio, using the HD Radio system from iBiquity; an HD2 subchannel currently runs iHeart's TikTok Radio CHR service, exclusively focused on songs popular on the app.
