平安（希伯来语：שָׁלוֹם‎，英语：Shalom；犹太-罗曼语支/以色列希伯莱语： Shalom；阿胥肯纳吉希伯莱语/意第绪语：Sholem、 Shoilem、 Shulem）是犹太人日常常用的祝福语，较为正式的场合则用全句「Shalom aleikhem」（愿平安与你常在，希伯来语：שָׁלוֹם עֲלֵיכֶם‎，shālôm ʻalêḵem；意第绪语：שלום־עליכם，sholem aleykhem），而回答是「aleikhem shalom」愿你与平安常在。和英语的「Peace be with you」相似，祝福人与人之间的平安，神与人之间的平安，或国与国之间的平安。和阿拉伯语的色兰（Salaam），马耳他语的「sliem」，叙利亚文的「Shlomo」等等的祝福语同出一源，亦皆常简写作S-L-M。

Shalom (שָׁלוֹם) (Sephardic Hebrew/Israeli Hebrew: shalom; Ashkenazi Hebrew/Yiddish: sholom, sholem, sholoim, shulem) is a Hebrew word meaning peace, harmony, wholeness, completeness, prosperity, welfare and tranquility and can be used idiomatically to mean both hello and goodbye. As it does in English, it can refer to either peace between two entities (especially between man and God or between two countries), or to the well-being, welfare or safety of an individual or a group of individuals. Stendebach and Ringgren writes that a more thorough etymological analysis of Hebrew roots reveal that 'Lom was the basic root word for Shalom. The word shalom is also found in many other expressions and names. Its equivalent cognate in Arabic is salaam, sliem in Maltese, Shlama in Syriac-Assyrian and sälam in Ethiopian Semitic languages from the Proto-Semitic root Š-L-M.
