Coyote en Ayuno, Colossal steel sculpture in Ciudad Nezahualcoyotl, Mexico.

Coyote en Ayuno is a red-painted steel sculpture on a roundabout at Adolfo López Mateos and Pantitlán Avenues in Ciudad Nezahualcóyotl. Built from flat, angled steel panels, it shows a coyote's head and neck looking skyward, with an open mouth and angular teeth. The complex, sculpture and concrete pedestal together, is 40 meters tall and 21 meters wide; the sculpture weighs about 300 metric tons.

Coyote en Ayuno was commissioned by then-mayor Luis Sánchez Jiménez with a budget of 2 million pesos and planned for completion within a year. The final cost reached 5 million pesos and the work took three years. It was inaugurated on 23 April 2008 for the municipality's 45th anniversary and was then the tallest sculpture in Mexico. A planned cultural centre and museum never materialised.

The name Coyote en Ayuno, also given as Coyote Hambriento and Cabeza de Coyote, refers to the etymology of Nezahualcóyotl. The red coyote gazes skyward, and its eyes face east so that on 23 April the first sunlight can cross the eye socket and project onto a commemorative plaque, a gesture the sculptor Sebastián likened to a pre-Hispanic ritual.

The sculpture stands at a busy intersection and can be viewed easily from surrounding roads. Visitors can approach within a few meters of the base but should watch for traffic.

The original project also planned a cultural centre and museum in the complex, but neither was built.
