阿卜杜勒-迈吉德一世（1823年4月23/25日－1861年6月25日，奥斯曼土耳其语：عبد المجيد اول），是奥斯曼帝国的第三十一任苏丹，于1839年7月2日继承其父马哈茂德二世而登基。

他在任期间须面对帝国各地民族主义运动的挑战。他尝试推行奥斯曼主义以提高分离主义者对帝国的归属感，以遏止民族主义运动。尽管阿卜杜拉·迈吉德一世推行新的法例及改革，致力将国内非穆斯林及非土耳其人融合到奥斯曼帝国的社会，但未能成功。

他亦尝试巩固与西欧主要势力的关系，即英国、法国，并在克里米亚战争并肩作战，对抗俄国。在1856年3月30日的巴黎会议里，奥斯曼帝国被承认为欧洲国家。阿卜杜勒-迈吉德一世最大的成就是推行坦志麦特改革，该改革由其父马哈茂德二世开始制定，结果成功使土耳其于1839年现代化。

Abdülmecid I (Ottoman Turkish: عبد المجيد اول ‘Abdü’l-Mecīd-i evvel; 23/25 April 1823 – 25 June 1861), also known as Abdulmejid and similar spellings, was the 31st Sultan of the Ottoman Empire and succeeded his father Mahmud II on 2 July 1839. His reign was notable for the rise of nationalist movements within the empire's territories. Abdülmecid wanted to encourage Ottomanism among the secessionist subject nations and stop the rise of nationalist movements within the empire, but failed to succeed despite trying to integrate non-Muslims and non-Turks more thoroughly into Ottoman society with new laws and reforms. He tried to forge alliances with the major powers of Western Europe, namely the United Kingdom and France, who fought alongside the Ottoman Empire in the Crimean War against Russia. In the following Congress of Paris on 30 March 1856, the Ottoman Empire was officially included among the European family of nations. Abdülmecid's biggest achievement was the announcement and application of the Tanzimat (Reorganization) reforms which were prepared by his father and effectively started the modernization of the Ottoman Empire in 1839. For this achievement, one of the Imperial anthems of the Ottoman Empire, the March of Abdülmecid, was named after him.
