Avanyu (sometimes Awanyu) is a deity of the Tewa people. The Tewa are Pueblo Native Americans who share the Tewa language and live around the Rio Grande River north of Santa Fe, New Mexico among the pueblo communities of Nambé,
Pojoaque, San Ildefonso, Ohkay Owingeh (San Juan), Santa Clara, and Tesuque. San Ildefonso and Santa Clara are in particular known for their pottery, which often has depictions of Avanyu.
Avanyu is the guardian of water and represents how important water is to the native peoples of the desert, with the flowing movement of its body suggesting the flow of water and the zigzag of the tongue symbolizing lightning. The serpent, often depicted with plumes or horns, appears in cave drawings in New Mexico and Arizona and remains a common decorative motif on the pottery of a number of Southwestern tribal potters. It’s been suggested that Avanyu might be related to Quetzalcoatl and other feathered serpent gods from Mesoamerican cultures.
