In Welsh mythology, Cigva (or Cigfa) was the wife of King Pryderi of Dyfed.

Pryderi invited Manawydan to live with him in Dyfed after he married Rhiannon, Pryderi's mother. Soon, Dyfed turned into a barren wasteland and only Rhiannon (Pryderi's mother), Pryderi, Cigva and Manawydan lived. Manaywdan and Pryderi, while out hunting, saw a white boar which they followed. Pryderi and his mother, Rhiannon, touched a golden bowl that the boar led them to and became enchanted. Manawydan and Cigva were unable to help them until they captured a mouse which was actually the wife of Llwyd, Rhiannon's enemy, and the spell was lifted.
