马格里布（al-Maġrib al-ʿArabī，المغرب العربي‎），非洲西北部一地区，阿拉伯语意为“日落之地”。宋代《诸蕃志》译为「默伽猎」。

该词在古代原指阿特拉斯山脉至地中海海岸之间的地区，有时也包括穆斯林统治下的西班牙部分地区，后逐渐成为摩洛哥、阿尔及利亚和突尼斯三国的代称。该地区传统上受地中海和阿拉伯文明影响，同时也与撒哈拉沙漠以南的黑非洲地区有着密切的贸易往来，因此形成了独特的文化。

19世纪末，该地区绝大部分成为法国、西班牙和意大利的殖民地。今日，除休达和梅利利亚两个地区尚属于西班牙外，其他地区均已合并入摩洛哥、阿尔及利亚和突尼斯三国。

The Maghreb (/ˈmæɡrɪb/ or /ˈmʌɡrəb/; literally "sunset"; Arabic:المغرب العربي‎ al-Maghrib al-ʻArabī, "the Arab West"; Berber: ⵜⴰⵎⴰⵣⵖⴰ Tamazgha; previously known as Barbary Coast), or the Greater Maghreb (Arabic:المغرب الكبير‎ al-Maghrib al-Kabīr), is usually defined as much or most of the region of western North Africa or Northwest Africa, west of Egypt. The traditional definition as the region including the Atlas Mountains and the coastal plains of Morocco, Algeria, Tunisia, and Libya, was later superseded, especially following the **** formation of the Arab Maghreb Union, by the inclusion of Mauritania and of the disputed territory of Western Sahara (mostly controlled by Morocco). During the Al-Andalus era in Spain (711–1492), the Maghreb's inhabitants, Maghrebis, were known as "Moors"; the Muslim areas of Spain in those times were usually included in contemporary definitions of the Maghreb—hence the use of "Moorish" or "Moors" to describe the Muslim inhabitants of Spain in Western sources.
