MTVU (formerly stylized as MtvU and mtvU) is an American digital cable TV channel owned by the MTV Entertainment Group, a unit of the Paramount Media Networks division of Paramount Global. The channel was first known as VH1 Uno from 2000 to 2004 before changing names when Viacom expanded MTVU programming beyond more than 750 college and university campuses across the United States, as part of internally originated cable systems that are a part of on-campus housing or college closed-circuit television systems to digital cable in all homes. Music videos played on the channel primarily consist of indie rock, pop punk and hip-hop along with limited original programming. MTVU also launched a short-lived campus guide and social media network called Campusdailyguide.com in 2008.

In 2018, the MTV Networks on Campus group was sold by Viacom to Cheddar to launch CheddarU, but the digital cable channel remains available to the public through digital cable.
