KFNZ (610 AM) is a broadcast radio station in the United States. Licensed to Kansas City, Missouri, KFNZ broadcasts a sports radio format simulcasting much of KFNZ-FM; both stations are owned by Audacy, Inc. Programming includes local sports talk shows, the Fox Sports Radio network, and live coverage of Kansas City Chiefs football, Kansas City Royals baseball, and Kansas State University football and basketball.

The station was first licensed in 1922 with call sign WDAF, founded by The Kansas City Star. It became an NBC Red Network affiliate. In 1957, the Star sold WDAF to National Theatres in order to settle an antitrust lawsuit; WDAF would later be bought by Transcontinental Television in 1960 and Taft Broadcasting in 1964. Beginning in the 1960s, the station had a pop standards music format, followed by country music from 1977 to 2003. With personalities including Bob "Hoolihan" Wells and Walt Bodine, WDAF had been among the most popular radio stations in Kansas City from the 1960s to 1990s, ranked as high as no. 1 in Arbitron local ratings in the 1980s and early 1990s; in 1983, the station was even ranked among the top 25 nationally in morning drive ratings by Radio & Records.

In 2003, WDAF changed its call sign to KCSP and picked up its current sports format, with Jason Whitlock among its inaugural hosts. In 2024, KCSP changed to KFNZ and a simulcast of KFNZ-FM.
