KTBW-TV (channel 20) is a religious television station licensed to Tacoma, Washington, United States, serving the Seattle area as an owned-and-operated station of the Trinity Broadcasting Network (TBN). The station's studios are located on South 341st Place in Federal Way, and its transmitter is located on Gold Mountain near Bremerton.
KTBW originally signed on the air with the call sign KQFB on March 30, 1984. As KQFB, the station was originally locally owned by Family Broadcasting based in University Place, Washington. Family Broadcasting originally was going to broadcast Christian programming from several sources. Before the station went on the air, a minority interest in KQFB was acquired by the Trinity Broadcasting Network. When TBN acquired Family Broadcasting in full, the call letters were changed to KTBW on December 18, 1984.
