Ali Nijat Sirel (1897 Amasya – 1959 İstanbul) was a Turkish sculptor. The that he made in 1931 together with Mahir Tomruk is considered one of his best works. He is one of the first sculptors to take over monument sculpture in Turkey from foreigners. He is an important figure for Turkish sculpture as he and Mahir Tomruk are among the teachers to first educate the Republic-era Turkish sculptors. In 1915, he was sent to Germany on a state scholarship to study sculpture. He was educated at the Munich Fine Arts Academy, after which he returned home.
