'''Franz Yulievich Levinson-Lessing''' ({{langx|ru|Фра́нц Юльевич Левинсо́н-Ле́ссинг}}), or ''Theodor Levinson-Lessing'' (March 9, 1861 &ndash; October 25, 1939 in St. Petersburg<ref>Tomkeieff S.I. Franz Youlievich Loewinson-Lessing // Quart. Journ. Geol. Soc. London. 1940. Vol. 96. P. xiv-xvi.</ref>) was a Russian geologist.

He graduated from the physico-mathematical faculty of the University of St. Petersburg in 1883, was placed in charge of the geological collection in 1886, and was appointed privat-docent at St. Petersburg University in 1889. In 1892 he became professor, and the next year dean, of the physico-mathematical faculty of Yuryev University (today University of Tartu). Aside from his work on petrography he published also essays in other branches of geology, the result of scientific journeys throughout Russia.

An island in the Kara Sea was named after this prominent Russian geologist.
