St. Monegundis was a French hermit who lived during the sixth century. A native of Chartres, she married and bore her husband two daughters.
When her daughters died in childhood, she decided to enter a monastery after receiving permission from her husband. She founded a hermitage, consisting of a private room, at Chartres but later moved to a site near the tomb of St. Martin in Tours.
She acquired a reputation for holiness. She was joined by other women, and Monegundis devised a monastic rule, eventually founding the convent of St. Pierre-le-Puellier.
