Bulcsú (or Vérbulcsú) (died 10 August 955) is a Hungarian chieftain, one of the military leaders of prince Taksony of Hungary, a descendant of Árpád.

He holds the title of horka.

He is one of the more important figures of the Hungarian invasions of Europe.

During these military campaigns, the Magyars threaten much of Western Europe; therefore a common saying at this time is "A sagittis Hungarorum, libera nos Domine" (Lord, save us from the arrows of the Hungarians").

He is executed after the disastrous Battle of Lechfeld, also known as the Battle of Augsburg.
