In Aztec mythology, Tōnacacihuatl (Classical Nahuatl: Tonacacihuātl; pronounced: /toːnakaˈsiwaːt͡ɬ/) was a creator and goddess of fertility, worshiped for peopling the earth and making it fruitful. Most Colonial-era manuscripts equate her with Ōmecihuātl. Tōnacācihuātl was the consort of Tonacatecuhtli. She is also referred to as Ilhuicacihuātl or "Heavenly Lady."
