Dentelin of Mons was a Frankish saint who lived during the 7th century. Born in Austrasia to the saintly parents Waltrude and Madelgaire, he was the fourth child of the couple. His life was brief, as he died in Hainoensis at approximately seven years of age. Although he lived a short life, his holy parentage and early death led to his recognition as a saint in the Catholic and Orthodox traditions.
