K36DU, UHF analog channel 36, was a low-power Worship Network-affiliated television station licensed to Lake Havasu City, Arizona, United States.^[1] The station was owned by Richard D. Tatham. K36DU's transmitter was located at the BLM communications site on Goat Hill, approximately five miles (8 km) north of Lake Havasu City.^[2]

K36DU was founded on March 4, 1994 with an original construction permit granted to Richard D. Tatham of Lake Havasu City. The station was licensed on April 5, 1996 and converted to Class A status on September 10, 2001. The station surrendered its class A license to the Federal Communications Commission (FCC) on April 8, 2013, and reverted to a standard low-power license.

K36DU's license was cancelled by the FCC on August 4, 2021, due to the station failing to obtain a license for digital operation by the July 13 deadline.^[3]
