MyNetworkTV is a television network in the United States, owned by News Corporation. It is the lowest-rated of the six major US English-language commercial broadcast networks.

The network began operations on September 5, 2006 with an initial affiliate lineup covering about 96 percent of the country, most of which are former WB and UPN affiliates. Its original primetime format consisted of hour-long soap operas that aired on a five-nights-per-week, 13-week pattern.

After failing to attract viewership with that format, the network revamped its schedule in 2007 to a lineup aimed towards young males (a la Spike), with movies and mixed martial arts reducing telenovelas to one night per week. The network has ceased production of scripted programming.

MyNetworkTV is a sister network to the FOX network, but operates separately.
