Mehmet Niyazi Cemali (Crimean Tatar: Memet Niyaziy; January or February 1878 – November 20, 1931) was an Ottoman-born Romanian and Crimean Tatar poet, journalist, schoolteacher, academic, and activist for ethnic Tatar causes. Present for part of his life in the Russian Empire and Crimea-proper, he wrote most of his works in Crimean Tatar and Ottoman Turkish.
