Mordecai Plungian (Marcus Plungianski; 1814-1883) was a Lithuanian rabbi, Talmudist, and Hebrew author associated with the maskilim, or the writers of the haskalah movement (the Jewish enlightenment).

[1][2][3][4][5] He was born in Plungė and built a reputation as a Talmudist at a young age before moving to Troki, where his new ideas offended the ultra-conservatives, so he moved to Wilna, where he gave rabbinical lectures and began secular studies, including European literature and languages.

He got a job as a high school teacher before becoming an instructor of Talmud at the rabbinical seminary in 1867.

[6] His 1856 book Ben Porat was the subject of a censorship controversy, but he received assistance from Abraham Firkovich.
