Chanoch Henoch Eigis (Yiddish: חנוך העניך אייגעש; 1863–1941), known as the Marcheshet, was a prominent Lithuanian rabbi in the first half of the 20th century.
Throughout his career he maintained a close, personal relationship with the leader of the ultra-orthodox community in Vilna, Rabbi Chaim Ozer Grodzinski and the two jointly signed numerous petitions, letters and announcements.
The two rabbis jointly founded a kollel – a yeshiva for advanced rabbinic scholars who studied on their own –attended by many of the best talmudic students in Lithuania.
He continued to work in support of Aliyah (emigration of Jews to indigenous Israel) and in 1935 he was one of the founders of the ultra-orthodox department of the Jewish National Fund.
Eigis' wrote the books of responsa entitled Marcheshet, which deal both with practical and theoretical issues of Jewish law and was published in two parts, in 1931 and 1935.
