Inayat Rehmat Khan Pathan () (5 July 1882 – 5 February 1927) was the founder of the Sufi Order in the West in 1914 (London) and teacher of Universal Sufism. He initially came to the West as a Northern Indian classical musician, having received the honorific "Tansen" from the Nizam of Hyderabad, but he soon turned to the introduction and transmission of Sufi thought and practice. Later, in 1923, the Sufi Order of the London period was dissolved into a new organization, formed under Swiss law, called the "International Sufi Movement".
