KCYZ (105.1 MHz) is a commercial FM radio station in Ames, Iowa, broadcasting to the Des Moines metropolitan area.

KCYZ is Ames' FM home for Iowa State Cyclones college football and men's basketball, simulcasting with sister station KASI 1430 AM.

When it started life on June 20, 1968, KCCQ was one out of two Top 40 stations broadcasting in Central Iowa, including the Des Moines radio market.

When the early 1980s, rolled along, the station faced Top 40 competition against KRNQ, KIOA-AM, and KMGK (later KDWZ).

With its improved signal, KCCQ and KASI were sold in 1999, to Jacor, which later merged with Clear Channel Communications, the forerunner to today's iHeartMedia.
