Bertha of Val d'Or (birth unknown, death c. 690), was an abbess, virgin, and martyr, and is venerated in the Roman Catholic Church as a saint. Her husband was Gombert, Lord of Champenois, who was a nobleman and member of the royal family of France, with whom she lived "a celibate life". The legend of Bertha's life is "very late and unreliable. Laurent Majoret wrote a vita that was first published in Toul in 1650 and reissued in Rheims in 1700 and in 1743. Bertha's feast day is May 1.
