Iztapalapa is one of the Federal District of Mexico City’s 16 boroughs, located on the east side of the entity. The borough is named after and centered on the formerly independent municipality of Iztapalapa, which is officially called Iztapalapa de Cuitláhuac for disambiguation purposes. The rest is made up of a number of other communities which are governed by the city of Iztapalapa.

The borough is the most populous and fastest growing of the city with over 90% of its territory urbanized. The borough transitioned from a rural area with some farms and canals as late as the 1970s, to an area with the only green areas in parks and almost all of its people employed in commerce, services and industry. This is the result of a large influx of people into the borough starting from the 1970s and which still continues. The area has a high level of socioeconomic marginalization, with a significant number of people lacking sufficient access to clean potable water. Crime is also a major problem, with much of it related to drug trafficking and poverty. However, the borough is home of one of Mexico City’s major cultural events, the annual Passion Play in which 450 borough residents participate and about 2 million attend as spectators.
