Nasiruddin Mahmud Chirag-Dehlavi (Urdu نصیرالدین چراغ دہلوی ) (c. 1274–1337) was a 14th-century mystic-poet and a Sufi saint of the Chishti Order. He was a disciple of Sufi saint Nizamuddin Auliya, and later his successor. He was the last important Sufi of the Chishti Order from Delhi. Dehlavi's followers called him "Roshan Chirag-e-Delhi", which in Persian, means "Illuminated Lamp of Delhi".
