Mehmet Nasrullah (محمد نصرالله; fl. c. 1890 - 1910) was one of the most prominent geographers of the late Ottoman period. He is best known for his Atlaslı coğrafiya-yi Osmani and other atlases, but he also produced a series of wall maps with Tefeyyüz Kitaphanesi. In some biographies, he is noted as being a haji. He may be the same person as one al-Hac Nasir al-Dagistani, in which case he likely would have been a native of Dagestan in the Caucasus.
