Chaya Mushka (Moussia) Schneerson (Yiddish: חיה מושקא שניאורסאן; March 16, 1901 – February 10, 1988), referred to by Lubavitchers as The Rebbetzin, was the wife of Menachem Mendel Schneerson, the seventh and last rebbe (spiritual leader) of the Chabad-Lubavitch branch of Hasidic Judaism.

In May 1924, she moved with her family to Leningrad, where her father was forced to go after several years of being singled out for persecution by the local Jewish section of the Communist Party in Rostov.

[3] In the autumn of 1927, her father was imprisoned for disseminating Torah observance, and she participated in successful efforts to have him released.

In 1928 she married Menachem Mendel Schneerson in Warsaw, and they went to live in Berlin, where he studied in a local university.

[8] Soon after her death, her husband founded a charitable organization, Keren Ha'Chomesh (Chomesh is an acronym of Chaya Mushka Schneerson), primarily working in women's religious, social and educational programs.
