Veronika of Desenice (died October 17, 1425) is the second wife of Frederick II, Count of Celje.
Little is known of her early life.
It is believed the name Deseniška derives from the village of Desinić in Croatia, where Frederick also had extensive estates, and it appears in the forms Dessnitz, Dessenitz, Desnicze, Teschnitz, Teschenitz, and Dessewitz in various historical sources.
Veronika is minor nobility and Frederick's father Hermann II is greatly opposed to the marriage.
The chronicles of the Counts of Celje suggest he had his son arrested and, while holding him prisoner, initiated a trial against Veronika accusing her of witchcraft.
She is acquitted by the court, but despite this incarcerated in Ojstrica Castle near Tabor and murdered (supposedly on the orders of Hermann II) by being drowned in 1425.
She is buried in Braslovče and a few years later Frederick arranges for her remains to be reburied at the Carthusian monastery at Jurklošter and in her memory also makes an endowment to the monastery at Bistra.
