The Miracula Nynie Episcopi (English: Miracles of Bishop Ninian) is an anonymously written 8th-century hagiographic work describing miracles attributed to Saint Ninian. It is considered a non-historical work, and copies are not widely extant.
It was used as a reference by Ailred of Rievaulx in composing his Vita Sancti Niniani (English: Life of Saint Ninian) in the 12th century, a document that was used by the politically ambitious Fergus of Galloway in resurrecting the long-defunct Bishopric of Galloway.
