Mehmet Nazım (April 21, 1922 – May 7, 2014; Sha'ban 23, 1340 AH – Rajab 8, 1435 AH) Commonly known as Sheikh Nazim, was a Turkish Cypriot Sufi Muslim sheikh and spiritual leader of the Naqshbandi tariqa.
Nazim was active in Turkish and Arabic language contexts. His name was therefore transliterated into English in various ways: Nazim Qibrisi (Turkish: Nazım Kıbrısi), indicating his homeland of Cyprus (Turkish: Kıbrıs), and Muhammad Nazim Adil al-Qubrusi al-Haqqani an-Naqshbandi (Arabic: محمد ناظم عادل القبرصي الحقاني النقشبندي). His name al-Haqqani is an honorific granted by his Sufi teacher Abdullah Fa'izi ad-Daghestani.
