WKAQ is a radio station in San Juan, Puerto Rico that broadcasts on 580 kHz with a Spanish language talk radio format. The station is currently owned by Univision Radio. Its programming is repeated on WUKQ, which broadcasts on 1420 kHz in Ponce, and WYEL which broadcasts on 600 kHz in Mayagüez. The station was the first radio station to broadcast in Puerto Rico.
