Ekatarina Velika (Serbian Cyrillic: Екатарина Велика, English: Catherine the Great), sometimes referred to as EKV for short, was a Serbian and former Yugoslav rock band from Belgrade, being one of the most successful and influential music acts coming out of former Yugoslavia.

Initially called Katarina II (Serbian Cyrillic: Kатарина II, English: Catherine II), the band had built up a devoted following that greatly intensified and expanded after the death of its frontman Milan Mladenović in 1994, which caused the band to dissolve. The group's core consisted of singer and guitarist Milan Mladenović, keyboardist Margita Stefanović and bassist Bojan Pečar, with other members mostly remaining for comparatively shorter periods.
