The 5th constituency of the Bas-Rhin is a French legislative constituency in the Bas-Rhin département.

The 5th Constituency of Bas-Rhin covers the southern portion of the Département including nearly the entire of the Arrondissement of Sélestat-Erstein excluding only Obernai.

The seat has traditionally been a stronghold of the right since its inception and was held by the Gaullist UMP/LR from 2002 to 2022, when the seat was gained by the moderate right Agir party, as part of Emmanuel Macron's centrist Ensemble Citoyens alliance.

[3] Antoine Herth was elected with more than 50% of the vote in the first round of voting, and therefore no second round took place.
