Wiborada of St. Gall (also Guiborat, Weibrath or Viborata; Alemannic: Wiberat) (died 926) was a member of the Swabian nobility in what is present-day Switzerland.

A pilgrimage to Rome influenced Hatto to decide to become a monk at the Abbey of Saint Gall, a decision which Wiborada supported.

After the death of their parents, Wiborada joined Hatto and became a Benedictine at the Abbey of Saint Gall.

[2] At this time, it appears that Wiborada was charged with some type of serious infraction or wrongdoing, and was subjected to the medieval practice of ordeal by fire to prove her innocence.

Her warning allowed the priests and religious of St. Gall and St. Magnus to hide the books and wine and escape into caves in nearby hills.

Wiborada's refusal to leave her cell and the part she played in saving the lives of the priests and religious of her convent have merited her the title of martyr.
