法塔赫（阿拉伯语：فتح‎；英语：Fatah）是巴勒斯坦民族解放运动（阿拉伯语：حركة التحرير الوطني الفلسطيني‎，英语：Palestinian National Liberation Movement）的简称。该组织成立于1959年，由亚西尔·阿拉法特创立，是巴勒斯坦解放组织中最大的派别。主要活动区域是约旦河西岸地区。法塔赫的最高权力机构是代表大会。代表大会在闭会期间由革命委员会行使职权，而革命委员会则负责选举产生中央委员会，同时领导该组织的日常工作。

“Fatah”源自“巴勒斯坦民族解放运动”一词在阿拉伯文（阿拉伯语：حركة التحرير الوطني الفلسطيني‎）中的英文译音转写（Ḥarakat al-Taḥrīr al-Waṭanī al-Filasṭīnī）的首字母缩略字。由于阿拉伯文的书写系统是从右往左，故用此英文转写在字面上其实是反向的。

Fataḥ (Arabic:فتح‎ Fatḥ), formerly the Palestinian National Liberation Movement (Levantine Arabic: [ˈfateħ]), is a secular Palestinian political party and the largest faction of the confederated multi-party Palestine Liberation Organization (PLO).

Fatah is generally considered to have had a strong involvement in revolutionary struggle in the past and has maintained a number of militant groups. Fatah had been closely identified with the leadership of its founder Yasser Arafat, until his death in 2004. Since Arafat's departure, factionalism within the ideologically diverse movement has become more apparent.
