College Basketball on NBC Sports is the de facto branding used for broadcasts of NCAA Division I men's college basketball games produced by NBC Sports, the sports division of the NBC television network in the United States. The NBC network broadcast college basketball games in some shape or form between 1969 and 1998. From 1969 to 1981, NBC covered the NCAA Division I men's basketball tournament. It became the first major network to broadcast the championship game, at a cost of more than US$500,000 in 1969.

In 2011, Comcast's sports channel Versus became part of NBC Sports after the company's acquisition of NBC Universal, and was relaunched as NBC Sports Network (NBCSN) in 2012. During the 2010s, NBCSN primarily carried coverage of basketball from the Atlantic 10 Conference, Colonial Athletic Association (CAA), and Ivy League.

NBCSN would lose the CAA and Ivy League, but retained its A-10 package. It was renewed in 2021 under a multi-year deal, and moved to USA Network in January 2022 after the shutdown of NBCSN. In August 2022, NBC Sports announced that it had acquired rights to Big Ten basketball as part of a larger agreement with the conference, with a package of games airing on Peacock beginning in the 2023–24 season.

On November 12, 2022, college basketball returned to the main NBC network when the Notre Dame women's college basketball team took on the California women's college basketball team as part of the inaugural Citi Shamrock Classic. It was the first women's college basketball game to ever air on NBC, and the first college basketball game of any kind since 1998. Men's college basketball returned to the main NBC network during the 2024–25 season.

NBC's relationship with college basketball dates as far back as February 28, 1940, when W2XBS (the future flagship station for NBC, WNBC) presented a doubleheader at New York City's Madison Square Garden. The University of Pittsburgh faced off against Fordham University, followed by Georgetown University against New York University.

For NBC's first year of tournament coverage in 1969, the network aired the consolation game nationally and the national semi-finals on a regional basis (which were held on a Thursday night). 1972 marked the final year that NBC aired the consolation game. The following year marked the first time that the Final Four was held on a Saturday, and was the first prime time championship game to air on NBC.

From 1969 to 1972, Final Four contests were split national telecasts. Because the NCAA Tournament wasn't seeded, but based on geography, the Final Four generally had two eastern and two western teams. NBC, with a prime-time slot, televised the eastern-oriented game in the east, and the western-oriented game in the west. It essentially was a split-national telecast, with the split occurring over the time, not simultaneous games. This inevitably created problems, such as when Louisville played UCLA in the late game in 1972, people in the east didn't see it. And, if the first game went into overtime, NBC couldn't close out the eastern window and open the western window. The western United States would get the end of the early game, but the east would still not get to see the late game. The secondary problem was that the east didn't get to see UCLA in the tournament until the title game.

By 1974, NBC was providing coverage of nine games in seven windows (a far cry from the current tournament coverage). The following year, NBC aired ten games in nine windows – presenting the regional finals as a tripleheader with regional coverage in the middle time slot; this was also the first year that Billy Packer covered the Final Four.
