Adolf Friedrich Stenzler (July 9, 1807 - February 27, 1887) was a German Indologist who was a native of Wolgast.
He initially studied theology and Oriental languages at the University of Greifswald under Johann Gottfried Ludwig Kosegarten (1792-1860), then furthered his education at the University of Berlin with Franz Bopp (1791-1861) and afterwards studied at the University of Bonn under August Wilhelm Schlegel (1767-1845). In 1829 he earned his doctorate, and continued his studies in Paris, where he attended lectures by Antoine-Léonard de Chézy (1773-1832) and Silvestre de Sacy (1758-1838). Afterwards he worked in the library of the British East India Company in London.
In 1833 he was appointed associate professor of Oriental languages at the University of Breslau, where in 1847 he became a full professor. At Breslau he was an instructor of Arabic and Persian, and later gave classes on Sanskrit and comparative linguistics. From 1836 he worked as curator of the university library.
Stenzler was a pioneer of Sanskrit studies in Germany, and also did extensive work involving Indian literature in the fields of law and medicine. In 1868 he published his best known work, a highly regarded textbook on Sanskrit grammar and vocabulary, titled Elementarbuch der Sanskrit-Sprache.
