KFLY (101.5 FM) is an American commercial country music radio station licensed to Corvallis, Oregon, that serves the Willamette Valley of west-central Oregon, including Eugene–Springfield, Corvallis–Albany–Lebanon, and Salem.

KFLY began broadcasting on October 1, 1966, broadcasting its AM sister station's Top 40 format, as KFLY-FM. In 1979, KFLY-FM changed call letters to KEJO. Through 1993, 101.5 KEJO had an automated adult contemporary format. In January 1994, the station changed back to the KFLY call letters and rebranded as "Flight 101" with Jones Radio Network's satellite-fed hot adult contemporary format. By 2000, the station was branded as "Mix 101-5 KFLY" under Clear Channel's ownership. After completing its move to KDUK-FM's tower in 2002, vastly increasing coverage, KFLY briefly stunted with quick song clips, and then flipped to active rock as “101-5 K-Fly” broadcasting from Eugene, Oregon.^[2][3]

On July 15, 2015, KFLY's entire airstaff was let go, indicating a format change was imminent.^[4] On July 30, 2015, at Noon, KFLY changed its format to adult album alternative, branded as "World Class Rock 101.5".^[5][6][7][8]

On June 4, 2017, KFLY dropped its AAA format and began stunting with a text-to-speech countdown (using Microsoft David) to 3 p.m. the following day. At that time, the station flipped to country as "US 101".^{[9][10][11][12]}
