Meaning & Origin
a unisex given name
Isabeau is a girl's baby name of French origin, a medieval French variant of Isabel, which is itself a form of Elizabeth meaning 'my God is an oath' or 'pledged to God.'
Isabeau of Bavaria (1370–1435), Queen of France as wife of King Charles VI, is perhaps its most famous historical bearer — a controversial figure who navigated the turbulent Hundred Years' War. The name was also given new life in the 1985 fantasy film Ladyhawke, where it belongs to the enchanted heroine. Isabeau is rarer and more romantic-feeling than Isabella, appealing to parents who want medieval grandeur with a twist.
