Ilancueitl (Nahuatl for "old-woman skirt"; pronounced [ilaŋˈkʷeː.itɬ]) was the first queen of Tenochtitlan.

[3] Ilancuéitl was a daughter of the then ruler of Culhuacán, Acolmiztli[citation needed], and she married her nephew Acamapichtli, who thus became the first ruler of Tenochtitlan.

[4][5][6] She bore no children, so her husband took more wives.

[4] Ilancuéitl charged herself with the education of her stepson Huitzilihuitl.

Some sourced claimed that Ilancuéitl actually became ruler of Tenochtitlan herself.
