The Big 12 Network (stylized as the Big XII Network) was a syndicated package featuring live broadcasts of College basketball events from the Big 12 Conference that was broadcast under that branding from 2008 until 2014. It was owned and operated by ESPN Plus, the syndication arm of ESPN, Inc., and was mainly shown in areas in the Big 12’s geographical footprint, along with other areas of the United States. Games were shown locally on broadcast stations, regional sports networks, as well as on ESPN Full Court, and WatchESPN.

The Big 12 Network was available mainly in areas of the central United States, including much of Texas, Oklahoma, Kansas, eastern Nebraska, Iowa, Missouri, and western Arkansas. Other areas served by the Big 12 Network included parts of West Virginia, north-central and east-central Kentucky, Illinois, Indiana, Ohio, and southern Pennsylvania, especially during the 2012–2013 and 2013–2014 season. This was true because in 2012, Texas Christian University joined the Big 12 from the Mountain West Conference, and West Virginia University joined the Big 12 from the original Big East Conference. In spite of the University of Missouri (along with Texas A&M University) leaving the Big 12 to join the basketball-powerful Southeastern Conference in 2012, some stations in Missouri, especially in the Kansas City, Columbia, St. Louis, and Joplin markets, either kept the local rights to the Big 12 Network or lost them to another station in their home market.

In addition to the listed areas above, three independent stations in California also carried the syndication package. Throughout the 2008–2014 branding period, some Big 12 Network stations also broadcast football games from sister syndicator SEC TV, which provided Southeastern Conference football games to certain stations, most notably including KTXA/Dallas, Texas and KDOC-TV/Los Angeles, California, although KDOC also broadcast SEC TV basketball games on a limited schedule. This was especially true to some former Big 12 Network partners that switched to or altered to and from SEC TV broadcasts.
