WOI-FM (90.1 FM) is a radio station licensed to Ames, serving the greater Ames/Des Moines area. The station is owned by Iowa State University. WOI-FM is an affiliate of Iowa Public Radio, and is the flagship of IPR's "News and Studio One" service--a mix of National Public Radio news programming and adult alternative music.

WOI-FM first hit the airwaves on December 1, 1949. Like most FM stations of the time, it was originally a full-time simulcast of WOI (AM). The two stations went their separate ways in the 1960s.

Until the formation of Iowa Public Radio in 2004, WOI-FM was the flagship station for a mini-network of FM stations in central Iowa, including KWOI in Carroll and KTPR in Fort Dodge.

Shortly after midnight on September 10, 2012, the decades-old classical music and news format of WOI-FM was changed by IPR to their News and Studio One service. The classical service moved to WOI-FM's second digital subcarrier. For those without HD Radio, the classical continues to be heard in portions of central Iowa on other frequencies.
