Henri Eugene Xavier Louis Hyvernat (30 June 1858 – 29 May 1941) was a Franco-American Coptologist, Semitist and orientalist.

Henri Hyvnernat was born in Saint-Julien-en-Jarret (now part of L'Horme, Loire department) on 30 June 1858, the fifth of nine children of Claude and M. Leonide (née Meyrieux) Hyvernat.

[2] In 1897, he was appointed the first professor and founding director of the Department of Oriental Studies at the Catholic University of America in Washington, D.C.

In his research, he became interested in late antique, medieval and early modern history of the Christian Orient.

A large facsimile edition, Bybliothecae Pierpont Morgan Codice photo graphice expressi 56 volumes in 63 parts (Rome, 1922), which was published under the direction of Hyvernat is today an important source of Coptic studies.
