WGTK (970 kHz) is a commercial AM radio station in Louisville, Kentucky. It is owned by Word Media Group and it airs a conservative talk radio format. Similar to many Salem Media Group talk stations, it calls itself "970 The Answer." Its studios and offices are on Corporate Campus Drive in Louisville, while its transmitter is on Hamburg Pike in Jeffersonville, Indiana.

On weekdays, WGTK runs the entire line up of Salem Radio Network syndicated talk shows: Hugh Hewitt, Mike Gallagher, Dennis Prager, Michael Medved, Larry Elder and Joe Walsh. WGTK had aired a local midday show with former WHAS host Joe Elliott but that was discontinued in the Fall of 2015. The station begins most hours with co-owned Townhall Radio News. WGTK is the radio home of Bellarmine University men's basketball.

In the 1990s, the WGTK call letters belonged to a classic rock station in Middlebury, Vermont (now WWFY in Berlin). When Salem acquired an FM station in the Greenville-Spartanburg, South Carolina radio market, it used the same call letters, with that station known as WGTK-FM since February 2013.
