Johann Nepomuk Cosmas Michael Denis (27 September 1729 - 29 September 1800) was an Austrian poet, bibliographer, and lepidopterist.

He was born at Schärding on the Inn, brought up by the Jesuits, entered their order, and in 1759 was appointed professor in the Theresianum in Vienna, a Jesuit college. In 1784, after the suppression of the college, he was made second custodian of the court library, and seven years later became chief librarian.

A warm admirer of Klopstock, he was one of the leading members of the group of so-called bards; and his original poetry, published under the title Die Lieder Sineds des Barden (1772), shows all the extravagances of the bardic movement. He is best remembered as the translator of Ossian (1768-1769; also published together with his own poems in 5 vols. as Ossians und Sineds Lieder, 1784).

More important than either his original poetry or his translations were his efforts to familiarize the Austrians with the literature of North Germany; his Sammlung kürzerer Gedichte aus den neuern Dichtern Deutschlands, 3 vols. (1762-1766), was in this respect invaluable. He has also left a number of bibliographical compilations, Grundriss der Bibliographie und Bücherkunde (1774), Grundriss der Literaturgeschichte (1776), Einleitung in die Bücherkunde (1777), and Wiens Buchdruckergeschichte bis 1560 (1782).

In addition, working with Ignaz Schiffermüller he formed an early collection of butterflies and moths, which was kept at the Hofburg but lost in the revolution of 1848, and published the first catalog of the Lepidoptera found around Vienna.

Ossians und Sineds Lieder have not been reprinted since 1791; but a selection of his poetry edited by R. Hamel will be found in vol. 48 (1884) of Kürschners Deutsche Nationalliteratur. His Literarischer Nachlass was published by J. F. von Retzer in 1802 (2 vols.).
