Kaspar von Barth (June 21, 1587 – September 17, 1658) was a German philologist and writer. Barth was born at Küstrin in the Neumark region of Brandenburg. A precocious child, he was looked upon as a marvel of learning. After studying at Gotha, Eisenach, Wittenberg, and Jena, he travelled extensively, visiting most of the countries of Europe. Too independent to accept any regular post, he lived alternately at Halle and on his property at Sellerhausen near Leipzig. Because his library and manuscripts were destroyed by a fire at Sellerhausen, Barth moved to the Paulinum at Leipzig, where he died. Barth was a voluminous writer. Of his writings those considered to be most important are:
- Adversariorum commentariolum in 60 books (Frankfurt 1624, reprinted in 1658), a storehouse of miscellaneous learning, dealing not only with classical but also with medieval and modern writers
- commentaries on Claudian (1650)
- and Statius (1664).
