The ninth federal electoral district of Chiapas (Distrito electoral federal 09 de Chiapas) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 13 such districts in the state of Chiapas.
It elects one deputy to the lower house of Congress for each three-year legislative session by means of the first-past-the-post system. Votes cast in the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the third region.[1][2]
The ninth district was established as part of the 1977 electoral reforms. Under the 1975 districting plan, Chiapas had only six congressional districts;[3] under the 1977 reforms, the number increased to nine.[4] The newly created ninth district elected its first deputy, to the 51st Congress, in the 1979 mid-term election.

In 2005–2017, the district covered the north-eastern section of the municipality of Tuxtla Gutiérrez, approximating to the eastern half of the city together with a portion of its rural hinterland. The head town was the city of Tuxtla Gutiérrez.[9]
1996–2005

1978–1996
The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Chiapas's seat allocation rose from six to nine.[3] The new ninth district had its head town at Ocosingo and it covered 18 municipalities.[11]
