Adela of Pfalzel (d. 734 or 735), sometimes called Adula or Adolana, was a Frankish noblewoman, abbess, and Catholic saint. Some sources state that her father was Dagobert II and that her sister was Saint Irmina of Oeren. She married a man named Alberic; after he died, she entered the Benedictine monastery of Pfalzel, near Trier; she might have been the monastery's founder and first abbess. She died in Pfalzel in 735. Her feast day is on December 24 in the Orthodox Church; and on January 3 in the Catholic Church.
