The eighth federal electoral district of Chiapas (Distrito electoral federal 08 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.

Chiapas's eighth district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Chiapas had only six congressional districts; under the 1977 reforms, the number increased to nine. The newly created eighth district elected its first deputy, to the 51st Congress, in the 1979 mid-term election.

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, Chiapas's eighth district covers seven municipalities near the Guatemalan border:

• Bella Vista, Comitán de Domínguez, Chicomuselo, Frontera Comalapa, Socoltenango, La Trinitaria and Tzimol.

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the city of Comitán de Domínguez.

2017–2022

Between 2017 and 2022, the 8th district comprised a slightly different group of eight municipalities near the Guatemalan border: Comitán de Domínguez, Frontera Comalapa, Nicolas Ruiz, Las Rosas, Socoltenango, La Trinitaria, Tzimol and Venustiano Carranza.

2005–2017

In 2005–2017 the district covered another group of eight municipalities near the international border: Bella Vista, Chicomuselo, Comitán de Domínguez, Frontera Comalapa, La Independencia, La Trinitaria, Socoltenango and Tzimol. The head town was the city of Comitán.

1996–2005

Between 1996 and 2005, the eighth district had another slightly different configuration. Still in the same broad region and centred on Comitán, it covered the following municipalities:

• Comitán de Domínguez, La Independencia, La Trinitaria, Socoltenango and Tzimol, as in the 2005 plan, plus:
• Amatenango del Valle, Chanal, Las Rosas, and Teopisca.

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. The new eighth district had its head town at Tonalá and it covered six municipalities.
