Elḥanan Leib Lewinsky (Hebrew: אלחנן ליב לוינסקי; 21 March 1857 – 27 October 1910) was a Hebrew-language writer and Zionist leader.

[2] After the outbreak of the 1881–1884 pogroms, he abandoned his studies, joined the Zionist movement Hovevei Zion, and spent several months in Palestine in 1882.

After his return to Russia he became an active member of Hovevei Zion; he established Zionist organizations in southern towns of the Empire, while at the same time working as a grain merchant.

He himself considered 1889 as a starting point of the writing career, when he published several polemic articles against Sholem Aleichem and Yehoshua Ravnitski's ideas about the cultivation of Yiddish literature.

His views on the subject changed during the time, and later Lewinsky even founded Yiddish daily newspaper Gut morgen in Odessa.

[2] Lewinsky was a friend of the Zionist Ahad Ha'am and the poet Haim Nahman Bialik, and was one of the founders of the Moriah Publishing House.
