Texas is a state rather than a municipality, so **sister city relationships are usually maintained by individual Texas cities rather than by the state as a whole**.
- Many Texas cities, including **Houston, Dallas, San Antonio, Austin, Fort Worth, El Paso, and Corpus Christi**, participate in international sister-city programs. - Statewide twin-city designations are **not commonly referenced in the same formal way** as city-level partnerships. - For a precise list, it is best to consult the relevant city government or **Sister Cities International** entries for each Texas municipality.
