Hùng Vương or Vua Hùng (English: Hung King) is a title used in many modern discussions of the ancient Vietnamese rulers of the Hồng Bàng period. In antiquity this title began to be used for the ruler who was the religious and political leader of united ancient Vietnam. They were kings of Văn Lang of the Lạc Việt.

Legend tells of the dragon lord, Lạc Long Quân and the mountain fairy, (sometimes a Chinese immortal) Âu Cơ who had 100 sons. As the parents belonged to different realms, they parted ways, each taking 50 of the 100 sons to their respective homes. The eldest son went to live by the coast, in the domain of dragons.

The eldest came to power in 2879 BC and became known as Hùng Vương, ruling an area covering what is now North Vietnam and part of southern China. He founded the Hồng Bàng Dynasty, whose members ruled Vietnam until 258 BC. The dynasty existed in Vietnamese prehistory, so much of the lore from this time is now lost to the ages. The descendants took the title of Hùng Vương after the first king, and many Vietnamese folktales include mention them. Stories tell of the heroics of eighteen different Hùng Vươngs (one explains the introduction of the watermelon with the help of Hùng Vương X) but fail to account for the numerous unknown rulers of Vietnam during their two millennia of sovereignty.
