Veliki Brat (lit: Big Brother) is a Serbian version of the global reality show franchise Big Brother. The show is recorded and produced in Belgrade by Emotion Production.

Originally, the show began as a Serbian production with housemates from Serbia, Montenegro and Bosnia and Herzegovina. The third season also included housemates from Macedonia. For the fourth season Croatian broadcaster and producer RTL became involved, and auditions were held in Croatia, making the show Pan-regional.

In Serbia, the show was often broadcast by different channels. The first three regular seasons and three celebrity seasons were broadcast on B92 & Prva channel, while the other two celebrities and the fourth regular season were broadcast on Pink. In Montenegro the show is broadcast by Pink M and Prva, in Bosnia-Herzegovina by Pink BH, OBN and BN, in Macedonia by A1 and Sitel, and in Croatia the show is broadcast by RTL respectively.

After a one-year hiatus in 2012 and rumors of cancellation, producers announced that the show would be back in 2013 for a celebrity season. The fifth regular season was broadcast in late 2015.
