David Goratsiyevich Günzburg (Russian: Барон Давид Горациевич Гинцбург, David Goratsievich Gintsburg, 5 July 1857, Kamianets-Podilskyi - 22 December 1910, St. Petersburg), 3rd Baron de Günzburg, was a Russian orientalist and Jewish communal leader.
He was the son of Baron Horace Günzburg, who co-founded World ORT, a non-profit non-governmental organization whose mission is the advancement of Jewish and other people through vocational training and education, with past or present involvement in over 100 countries. His grandfather Joseph was ennobled in 1870 by the Grand Duchy of Darmstadt-Hesse and made baron in 1874.
Günzburg was born in present-day Ukraine, then part of the Russian Empire. He was educated at home, his teachers being Adolf Neubauer, Senior Sachs, and Hirsch Rabinovich. At the age of twenty he received the degree of "candidate" at St. Petersburg University, after having attended the lectures of Stanislas Guyard at Paris and Baron Rosen at St. Petersburg; later he studied Arabic poetry under Orientalist Wilhelm Ahlwardt (1828-1909) at Greifswald (1879–80).
He edited the Tarshish of Rabbi Moses ibn Ezra in a fascicle which was issued by the Meqitze Nirdamim Society, and prepared for the press the Arabic translation of the same work, with a commentary. He published also Ibn Guzman (Berlin), and wrote a series of articles on "Metrics", published in the memoirs of the Oriental Department of the Russian Archeological Society (1893) and of the Neo-Philological Society (1892), in the "Journal" of the Ministry of Public Instruction of Russia, and elsewhere.
