Steven Robert Dahl (born November 20, 1954) is an American radio personality. He is the owner and operator of the Steve Dahl Network, a subscription-based podcasting network. Dahl gained a measure of national attention after organizing and hosting Disco Demolition Night at Comiskey Park.

Originally, Dahl broadcast with Detroit stations WABX and WWWW and later with Chicago stations WCKG, WDAI, WLUP, WMVP and WLS. He served as a columnist for the Chicago Tribune in their Live section as the resident "vice advisor" until November 2010. He is also known in Chicago for his longstanding former role as one half of the Steve & Garry team (with Garry Meier), and the two are members of the National Radio Hall of Fame. Dahl is considered an influential shock jock in talk radio.

In addition to his radio career, Dahl is a singer, songwriter, and guitarist. His band, Teenage Radiation, recorded and performed a number of song parodies (which he often played on his show throughout the 1980s) and since 1990 he has performed and recorded as Steve Dahl and the Dahlfins. Dahl is also an occasional actor, and has appeared in films such as Grandview, U.S.A., Outing Riley and I Want Someone to Eat Cheese With.
