Sveigðir, Sveigder or Swegde (Old Norse "Waving One") was a Swedish king of the House of Yngling in Norse mythology. He was the son of Fjölner, whom he succeeded as king, and he married Vana of Vanaheimr, probably one of the Vanir. Lured by a dwarf, Sveigðir disappeared into a stone and never came back. He was succeeded by his son Vanlandi.
