Muzio Febonio (13 July 1597 – 3 January 1663) was an Italian priest and historian, best known for his historical and hagiographic works about Marsica, the Abruzzo sub-region where he was born.

In his writings he made extensive use of archive documents and historiographic and archaeological sources, showing a deep knowledge of them, although in a somewhat formal and pedantic style.

However, his works represent a valuable source of information for later historians, even if their publication occurred with a lot of errors and delays, which partly explains the limited fame this author enjoyed.

During the troubled stay in L'Aquila he received several accusations, later totally dropped, from the vicar of St. Cesidius' Chair in Trasacco, including those of simony and murder.

The first draft of the precious Historiae marsorum (Latin: History of the Marsi) would date back just to 1660, however, the work, made of three books, was terminated between 1661 and 1662, and in all likelihood, after some months, so was the revision with the stylistic corrections suggested by historian Ferdinando Ughelli, also considered by Febonio as a master of erudition.
