In Aztec mythology, Huēhuehcoyōtl ([weːweʔˈkojoːt͡ɬ]) (from huēhueh [ˈweːweʔ] "very old" (literally, "old old") and coyōtl [ˈkojoːt͡ɬ] "coyote" in Nahuatl) is the auspicious Pre-Columbian god of music, dance, mischief, and song.

He is the patron of uninhibited sexuality and rules over the day sign in the Aztec calendar named cuetzpallin (lizard) and the fourth trecena Xochitl ("flower" in Nahuatl).

[2][3] Stories derived from the Codex Telleriano-Remensis characterized Huehuecóyotl as a benign prankster, whose tricks were often played on other gods or even humans, but tended to backfire and cause more trouble for himself than for the intended victims.

He was a part of the Tezcatlipoca (Smoky Mirror) family of the Mexica gods and inherited their shapeshifting powers.

Huehuecóyotl shares many characteristics with the trickster Coyote of the North American tribes, including storytelling and choral singing.
