Zenonas Ivinskis (25 May 1908 in Kaušėnai village, near Plungė – 24 December 1971 in Bonn, West Germany) was a noted Lithuanian historian.
There, under the direction of prof. Albert Brackmann, he received a Ph.D. for his thesis Geschichte des Bauerstandes in Litauen (English: History of the Conditions of Lithuanian Farmers) in 1932.
In 1933 in Gdańsk he was habilitated for his work Lietuvių ir prūsų prekybiniai santykiai pirmojoje XVI a. pusėje (English: Lithuanian and Prussian trade in the first half of the 16th century).
Unlike most other Lithuanian refugees, he did not emigrate to the United States and chose to live in Germany.
The next year he received his second habilitation in Lithuanian and Polish history and was appointed as a full-time professor.
