(Latin: Onuphrius Panvinius; 23 February 1529 – 27 April 1568) was an Italian Augustinian friar, historian and antiquary who was the librarian to Cardinal Alessandro Farnese.

Refusing the position of bishop, he accepted the more welcome office of corrector and reviser of the books of the Vatican Library in 1556.

The scholarly printer Paulus Manutius called him antiquitatis helluo ("a glutton for antiquity"), and Julius Caesar Scaliger styled him pater omnis historiae ("father of all history").

[1] About the same time he began to collaborate with the French engraver Étienne Dupérac, who continued to provide illustrations for posthumous printings of Panvinio's works.

Not all of his numerous historical, theological, archaeological, and liturgical works were published, even posthumously; some are preserved in manuscript in the Vatican Library.
