WAKY (620 kHz) is a classic hits AM radio station in Louisville, Kentucky, that simulcasts WAKY-FM (103.5 MHz). It is owned by William Walters, through licensee W & B Broadcasting Co., Inc. The station used to share a significant portion of Spanish-language programming with sister station WTUV-FM (105.7) until WTUV-FM was sold to UB Louisville and became English-language sports radio station WHBE-FM. The original station call letters, under different owners, were WTMT (1958–2010) with country music and, later, sports formats.

WAKY is also simulcast on FM translators W261CO (100.1 FM), W285ER (104.3 FM) in Prospect, and W292FS (106.3 FM) in Louisville. W261CO serves Louisville inside the Interstate 264 (Watterson/Shawnee Expressway) corridor (along with New Albany, Clarksville, and Jeffersonville in Southern Indiana), W285ER serves Charlestown in Southern Indiana, and W292FS serves Jeffersontown and Lake Forest.

The station was assigned the WAKY call letters by the Federal Communications Commission on April 1, 2015. On May 3, 2015, the format was changed to a simulcast of WAKY-FM, rebroadcasting its classic hits format. The WAKY call letters are evocative of the famous WAKY (790 kHz), a nationally influential Top 40 music station in Louisville (under other ownership, including Gordon McLendon, Multimedia and LIN Broadcasting) from 1958 to late 1985. Currently, the WAKY-AM-FM studios are south of the Fort Knox Army Reservation in Radcliff, Kentucky, about 27 miles south of Louisville. The WAKY AM transmitter and antenna are located in the Oak Park area of Jeffersonville, Indiana.
