The Reformist Bloc (Bulgarian: Реформаторски блок, romanized: Reformatorski blok) was a centre-right[6][7][8][9] electoral alliance in Bulgaria.

In December 2015, DSB turned into opposition because of the discontent with the speed and depth of the judicial reform by the second government of Boyko Borisov.

In February 2017, the People's Party "Freedom and Dignity" left to join Lutvi Mestan's DOST.

Meglena Kuneva, the leader of Bulgaria for Citizens Movement, was placed as number one on the party's list.
