MyNetworkTV (unofficially abbreviated MyTV, MyNet, MNT or MNTV, and sometimes referred to as "My Network") is a television broadcast syndication service in the United States, owned by the Fox Entertainment Group, a division of News Corporation. Under its former status as a television network, it was the lowest-rated of the then-six major US English-language commercial broadcast networks.

MyNetworkTV is a sister company to the Fox network, but operates separately. Roger Ailes oversees the service as chairman of the Fox Television Stations Group (FTSG).

MyNetworkTV began operations on September 5, 2006 with an initial affiliate lineup covering about 96 percent of the country, most of which were former WB and UPN affiliates.

On September 28, 2009, following disappointment with the network's results, MyNetworkTV dropped its status of a television network and transitioned to become a syndication programming service, reminiscent of the Universal Action Pack and Warner Bros.' Prime Time Entertainment Network.

A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay TV providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (e.g. the BBC, NBC or CBS) evolved from earlier radio networks.

In countries where most networks broadcast identical, centrally originated content to all their stations and where most individual TV transmitters therefore operate only as large "repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency), and "television station" have become mostly interchangeable in everyday language, with professionals in TV-related occupations continuing to make a difference between them. Within the industry, a tiering is sometimes created among groups of networks based on whether their programming is simultaneously originated from a central point, and whether the network master control has the technical and administrative capability to take-over the programming of their affiliates in real-time when it deems this necessary — the most common example being national breaking news events.
