The Chichinautzin Biological Corridor is a protected natural area in central Mexico.

The corridor consists of two separate parts, which lie east and west of El Tepozteco National Park.

The eastern portion is bounded on the west by El Tepozeco National Park and on the northwest by Milpa Alta Protected Area.

Pine-oak forests are the main plant community in the corridor, with species of pine, oak, and oyamel (fir) as the predominant trees.

The Chichinautzin Biological Corridor is a protected natural area with a remarkable diversity of habitats and species due to its geographic and climatic conditions.
