西墙，又名哭墙（希伯来语：הַכֹּתֶל הַמַּעֲרָבִי‎，HaKotel HaMa'aravi；阿拉伯语：حائط البراق‎，Ḥā'iṭ Al-Burāq）位于耶路撒冷老城内，圣殿山山下西侧。这是环绕第二圣殿庭院的古城墙的残存部分。在四面墙之中，西墙被认为是当年最靠近圣殿的，使它成为犹太教信仰中除圣殿山本身以外最神圣的一个地点。

通常认为，西墙由大希律王兴建于公元前19年，但最近的发掘表明希律王生前并未完成此项工程。墙底部的大石块区段是于希律王时期修筑；上方中型石块区段于奥米亚王朝时期修筑；顶部小石块区段修筑时间于鄂图曼帝国时期之后。现存西墙总长488公尺，犹太人聚集祈祷的那段位在圣殿山西南端犹太区里的大广场，其他部分隐身在穆斯林区的建筑物后。

The Western Wall, Wailing Wall or Kotel (Hebrew:  הַכֹּתֶל הַמַּעֲרָבִי , translit.: HaKotel HaMa'aravi; Ashkenazic pronunciation: Kosel; Arabic:حائط البراق‎, translit.: Ḥā'iṭ al-Burāq, translat.: the Buraq Wall, or al-Mabka: the Place of Weeping) is an ancient limestone wall in the Old City of Jerusalem. It is a relatively small segment of a far longer ancient retaining wall, known also in its entirety as the "Western Wall". The wall was originally erected as part of the expansion of the Second Jewish Temple by Herod the Great, which resulted in the encasement of the natural, steep hill known to Jews and Christians as the Temple Mount, in a large rectangular structure topped by a huge flat platform, thus creating more space for the Temple itself and its auxiliary buildings.
