The 8th federal electoral district of Tamaulipas () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Tamaulipas.
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 second region.
The 8th district was created as part of the 1977 electoral reforms, which increased the state's seat allocation from six to nine. The three new districts returned their first deputies in the 1979 mid-term election.
The current member for the district, elected in the 2024 general election, is Jesús Antonio Nader Nasrallah of the National Action Party (PAN).
District territory Tamaulipas lost a district in the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections. The reconfigured 8th district is in the state's extreme south-east and comprises the 300 electoral precincts () that make up two of the state's 43 municipalities: Ciudad Madero (107 precincts) and Tampico (193 precincts).
The head town (), where results from individual polling stations are gathered together and tallied, is the city of Tampico. The district reported a population of 503,518 in the 2020 census.
