Aldobrandino I d'Este (c.1190 – 10 October 1215) was the Marquis of Este and Ferrara, both in Italy. He was co-ruler with his half-brother Azzo VII. He was also the father of Saint Contardo of Este, a posthumous son. His daughter Beatrice married King Andrew II of Hungary and thus became Queen of Hungary.
