KTKB-LD (channel 26) is a low-power television station licensed to Tamuning, Guam, serving the U.S. territory as an affiliate of The CW Plus. Owned by Chicago-based KM Communications, the station is operated by Marianas Media under a local marketing agreement (LMA). It is carried island-wide on cable channel 4 on MCV Broadband and GTA's GUdTV system (hence the CW 4 Guam branding).

Despite being a low-power television station, KTKB's signal covers all of Guam. It is also the territory's first fully digital commercial television station.

The station went on the air on April 20, 2009, though it received its construction permit on September 3, 2003. Like most of the television stations in Guam, KTKB followed a Tuesday through Monday schedule for its CW primetime lineup because of Guam being a day ahead of the United States. However, it was the first station in Guam to air first-run syndicated fare and classic shows, most of them from the Sony Pictures Television library, though programming from Universal Media Studios and Warner Bros. Television was added in September 2009. By April 2010, other stations in Guam, notably KTGM and KEQI-LP, began adding syndicated product.

KTKB was one of the few stations to still sign off overnight, doing so at 1 a.m. It did not actually go off-the-air; rather, it simply showed station promos and public service announcements.

In March 2010, KTKB launched a half-hour newscast, Guam News Watch, which competed with KUAM News and Pacific News Center at 6 p.m. and 10 p.m. The newscast was canceled on January 4, 2011.^[2] On March 31, the station paused operations,^[3] returning to the air on January 9, 2012.^[4]
