Shalom aleichem (/ʃəˌlɒm əˈleɪxəm, ˌʃoʊləm-/; Hebrew: שָׁלוֹם עֲלֵיכֶם šālōm ʿalēḵem [ʃaˈloːm ʕaleːˈxem], lit. 'peace be upon you')[1][2] is a greeting in the Hebrew language. When someone is greeted with these words, the appropriate response is aleichem shalom (עֲלֵיכֶם שָׁלוֹם, lit. 'unto you peace').[3][4] The term aleichem is plural, but is still used when addressing one person.
This form of greeting is traditional among Jews worldwide, and typically connotes a religious context. It is particularly common among Ashkenazi Jews.
