The Lahore Ahmadiyya Movement for the Propagation of Islam, is a separatist group within the Ahmadiyya movement that formed in 1914 as a result of ideological and administrative differences following the demise of Hakim Nur-ud-Din, the first Caliph after Mirza Ghulam Ahmad. Members of the Lahore Ahmadiyya movement are referred to by the majority group as ghayr mubāyi'īn and are also known colloquially as Lahori Ahmadis.

Ahmadiyya, officially the Ahmadiyya Muslim Jama'at (AMJ) is an Islamic messianic movement originating in British India in the late 19th century. It was founded by Mirza Ghulam Ahmad (1835–1908), who said he had been divinely appointed as both the Promised Mahdi and Messiah expected by Muslims to appear towards the end times and bring about, by peaceful means, the final triumph of Islam; as well as to embody, in this capacity, the expected eschatological figure of other major religious traditions. Adherents of the Ahmadiyya—a term adopted expressly in reference to Muhammad's alternative name Aḥmad—are known as Ahmadi Muslims or simply Ahmadis.
