Moritz Georg Weidmann (23 January 1686 – 3 May 1743) was a German bookseller and publisher based in Leipzig, accredited to the courts of Poland and the Electorate of Saxony. He was the son of the Moritz Georg Weidmann Senior. He entered the business in 1713 as a partner, and in 1717 took complete control of his father's bookstore, which his stepfather, Johann Ludwig Gleditsch, had managed for him since 1694.
