Ecatepec City, once officially San Cristóbal Ecatepec de Morelos, is a city in the State of Mexico and the seat of Ecatepec de Morelos Municipality; however, both the city and the municipality are often known simply as "Ecatepec". The name "Ecatepec" is derived from Nahuatl, and means "windy hill" or "hill devoted to Ehecatl". It was also an alternative name or invocation to Quetzalcoatl. "Morelos" is the last name of José María Morelos, a hero of the Mexican War of Independence.
