Johann Conrad Hinrichs (October 30, 1763 - September 22, 1813) was a German publisher and bookseller. Little is known of his early life. In 1796, Hinrichs became partners with August Leberecht Reinicke, who had founded a bookstore in Leipzig five years earlier. By 1801, Hinrichs ran the bookstore alone. Beginning in 1798, he published catalogs of all new published works in the past six months, an invaluable resource for the reading public. Hinrichs then moved into publishing books in the fields of travel literature, law, political science, and history. After his death, his business was run by his widow Christiane Wilhelmine Hinrichs, a sister of Reinicke, initially alone and from 1816 together with her nephew Christian Friedrich Adolf Rost, who became a partner in 1819, with the business publishing as 'J.C. Hinrichs'sche Buchhandlung.' It took on specialties in theology and Oriental Studies and survived into the 20th century.
