Diema Sport (Bulgarian: Диема Спорт) is a Bulgarian paid sports television channel, part of Nova Broadcasting Group, owned by United Group.

The channel broadcasts premium live sports events such as the Bulgarian A Football Group, Premier League.

It aired films and other series, as well as sports events mostly from the English and Spanish Football Leagues.

Later, most of these programs were moved to the other Diema Vision channels, as few people signed up for the service, and advertising proved more profitable.

All these channels under the Diema Extra package aired matches from the two highest echelons of the Bulgarian football championship, the matches for the Bulgarian Cup, matches from the English Premier League, First and Second Bundesliga and French League 1, League Cup and FA Cup, German Football Cup, NBA basketball matches, Bulgarian volleyball championships, Formula 1 races and many other sports events.
