KSBJ (89.3 FM) is a non-commercial Christian adult contemporary radio station based in Humble, Texas, broadcasting to the Greater Houston area.

KSBJ is a non-profit ministry supported by listeners and is led by a diverse board of directors from across the greater Houston area.

KSBJ Educational Foundation also operates NGEN Radio, which is an online-exclusive Christian hip-hop and pop format, and the Spanish-language Vida Unida Christian AC format, which originates from sister station KHVU.

It first acquired low power translators in order to cover more potential listeners in areas outside of the main KSBJ signal range, then acquired full power facilities, beginning with KIOX-FM in El Campo.

While this greatly improved the signal in Houston itself, as well as the immediate suburbs in Harris County, KSBJ was all but lost in areas such as Livingston, Beaumont, and Huntsville, Texas.
