Gustav Leberecht Flügel (February 18, 1802 - July 5, 1870) was a German orientalist.
Born at Bautzen, he received his early education at the gymnasium of his native town, and studied theology and philology at Leipzig. Gradually he devoted his attention chiefly to Oriental languages, which he studied in Vienna and Paris. In 1832 he became professor at the Fürstenschule of St Afra in Meissen, but ill-health compelled him to resign that office in 1850, and in 1851 he went to Vienna, where he was employed in cataloguing the Arabic, Turkish and Persian manuscripts of the court library. He died at Dresden on the 5th of July 1870.
Flügel's chief work is an edition of the bibliographical and encyclopaedic lexicon of Haji Khalfa , with Latin translation (7 vols, London and Leipzig, 1835-1858). He also brought out an edition of the Qur'an (Leipzig, 1834 and again 1893); then followed Concordantiae Corani arabicae (Leipzig, 1842 and again 1898); Mani, seine Lehren und seine Schriften (Leipzig, 1862); Die grammatischen Schulen der Araber (Leipzig, 1862); and Ibn Kutlulbugas Krone der Lebensbeschreibungen (Leipzig, 1862). An edition of Kitab-al-Fihrist , prepared by him, was published after his death.
