Bertila de Chelles was a 7th-century Frankish abbess born in Soissons to a prominent family. After being educated at the Jouarre monastery under Saint Thelchildis, she was appointed as the first leader of Chelles Abbey in 646.

She was noted for her intense asceticism and her commitment to monastic discipline throughout her life.
