The 5th constituency of Pyrénées-Atlantiques (French: Cinquième circonscription des Pyrénées-Atlantiques) is a French legislative constituency in Pyrénées-Atlantiques departments.

Like the other 576 French constituencies, it elects one member of the National Assembly using the two-round system, with a run-off if no candidate receives over 50% of the vote in the first round.

In the 2017 legislative election, Florence Lasserre-David of the Democratic Movement (MoDem) won a majority of the vote.
