Colonia La Cuarta Transformación

Colonia La Cuarta Transformación is a neighborhood (Spanish: colonia) in Tultitlán Municipality, State of Mexico. It was originally part of the ejido San Francisco Chilpan. In November 2024, under the administration of Elena García Martínez—the outgoing municipal president and member of the Morena political party—three areas—Fimesa II, Fimesa III, and El Paraje—were merged to form the colonia. The municipal authorities established it without prior notice or consultation with local residents and modified the postal codes. A few weeks later, in December, García Martínez's successor, Ana María Castro Fernández, installed the street signs reflecting the name changes.

Previously, the streets had different thematic names, primarily related to flora. Following the modification, they were renamed after concepts and projects associated with Andrés Manuel López Obrador, who served as president of Mexico from 2018 to 2024 and the founder and former leader of Morena. During his tenure, López Obrador promoted the political platform known as the Fourth Transformation (La cuarta transformación).

Residents expressed dissatisfaction with the name change, who expressed concern over the administrative burden of updating personal documents. In response, they removed the street signs, and the state authorities agreed to suspend the name changes until a public consultation could be conducted, an action the municipal authorities have opposed.
