Aire Cathedral is a Roman Catholic church dedicated to Saint John the Baptist in the town of Aire-sur-l'Adour in the Landes département of France.
It was the seat of the Bishops of Aire until the diocese was abolished in 1801 and again from 1822 when the diocese was restored; in 1857 it was renamed the Diocese of Aire and Dax. In 1933 the bishop moved to Dax, making Dax Cathedral his seat, when the cathedral at Aire became a co-cathedral.
It was listed as a national monument in 1906.
