Third Federal Electoral District of Chiapas
The Third Federal Electoral District of Chiapas (III Distrito Electoral Federal de Chiapas) is one of the 300 Electoral Districts into which Mexico is divided for the purpose of elections to the federal Chamber of Deputies and one of 12 such districts in the state of Chiapas. It elects one deputy to the lower house of Congress for each three-year legislative period, by means of the first past the post system. District territory
The Third District of Chiapas is located in the extreme east of the state and covers much of the Lacandon Jungle. It comprises the municipalities of Altamirano, Benemérito de las Américas, Chanal, Las Margaritas, Maravilla Tenejapa, Marqués de Comillas, Ocosingo and Oxchuc. The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the city of Ocosingo. Previous districting schemes

1996–2005 district
Between 1996 and 2005, the Third District was broadly the same as under the current scheme, with the following differences:
Chanal was a part of the  Eighth District. The Third District also included San Juan Cancuc and Sitalá. Benemérito de las Américas, Maravilla Tenejapa and Marqués de Comillas had not yet been given municipal status; however, they belonged to the municipality of Ocosingo and so were included in the district by that token. Deputies returned to Congress from this district
