Oliver of Ancona

Saint Oliver of Ancona - also known as Oliver of Portonuovo, Oliverius or Liberius - († ca. 1050), is a saint of the catholic and orthodox Christian churches. His day is 3 February.

He was a Benedictine monk from Santa Maria di Portonuovo, a community at the foot of Monte Conero, south of Ancona on the Italian Adriatic coast.

It is thought that he came from Armenia, or that he originally was a Camaldolese monk from Dalmatia. Else, basically nothing is known about St Oliver of Ancona.

Another saint with the name Oliver is Oliver Plunkett, an Irish monk of the 17th century.
