Johann Peter Kirsch (3 November 1861 – 4 February 1941) was a Luxembourgish ecclesiastical historian and biblical archaeologist.

At the age of ten, he went to live with his maternal uncle, Johann Jakob Didier, a priest at Fels.

In the spring of 1888, he and Francesco Saverio Cavallari studied inscriptions and catacombs in Syracuse; in Naples he examined lead bulls.

[4] From 1889 to 1932 he was professor of patristics and biblical archaeology at the University of Fribourg,[3] where Clemens August Graf von Galen was one of his students.

In 1925, Pope Pius XI asked Kirsch to direct the Pontificio Istituto di Archeologia Cristiana in Rome.
