KUAL-FM (103.5 MHz; "Cool 103.5") is a radio station licensed to Brainerd, Minnesota, United States. The station is owned by Hubbard Broadcasting, Inc. and the broadcast license is held by HBI Radio Brainerd/Wadena, LLC. KUAL broadcasts an oldies/classic hits format. During the holiday season, the station broadcasts holiday music along with the program "This Was Christmas".

KUAL is a sister station to KVBR 1340 (business news/talk), KLIZ 1380 (sports), KBLB 93.3 (country), WJJY-FM 106.7 (adult contemporary), and KLIZ-FM 107.5 (classic rock). All are located in a brand new modern broadcast facility located at 13225 Dogwood Drive, Baxter.

KUAL previously aired a country music format as KFGI "Froggy 103.5". In or around 2004, KFGI flipped to its current oldies format, branded as "Cool 103.5, Good Time Oldies", under the new call sign KUAL.

Hubbard Broadcasting announced on November 13, 2014, that it would purchase the Omni Broadcasting stations, including KUAL-FM. The sale was completed on February 27, 2015, at a purchase price of $8 million for the 16 stations and one translator.

In recent years, KUAL has shifted away from a 1950s and 1960s-centered oldies format more towards a classic hits-leaning 1960s and 1970s oldies format. To reflect these changes, KUAL dropped the "Good Time Oldies" slogan and adopted "The Lakes Greatest Hits" as its new slogan. Sister station KULO in Alexandria, which closely resembled KUAL format wise, made a similar move, but shifted more towards a 1980s-centered classic hits format.
