Idh-yaa (The Mighty Mother) is a deity in the Cthulhu Mythos, who gave birth to the Star-Spawn of Cthulhu on a planet in the Xoth Star system, after matting with Cthulhu. She specifically produced the sons of Cthulhu: Ghatanothoa, Ythogtha, and Zoth-Ommog; and a daughter of Cthulhu: Cthylla. Also once called Quum-yaa.
Idh-yaa was created by Lin Carter.
