Isaac ben Moses Rumsch (Hebrew: יצחק בן־משה רומש, romanized: Yitsḥaḳ ben-Mosheh Rumsh; 6 April 1822 – 21 August 1894) was a Lithuanian Hebrew writer, translator, and educator.

Isaac Rumsch was born in the village of Zezemer.^[1] At the age of nine he went to Vilna, where he studied the Talmud in the yeshiva of his brother Joseph Rumsch, and then in that of Rabbi Mordecai Melzer [he]. Subsequently he acquired a knowledge of German and other secular subjects; but his plan of going to Germany to obtain a scientific education was frustrated by his disapproving relatives. When in 1853 the Russian government opened public schools for Jewish children in the government of Vilna, he, together with his friend Judah Löb Gordon, was appointed a teacher in the school of Ponevyezh.^[1]

Besides numerous novels, he contributed articles to Ha-Karmel and Ha-Melitz and left in manuscript some Hebrew stories and notes on the Bible.
