Bolâhenk Nuri Bey (b. in Istanbul, Ottoman Empire in 1834 - d. Istanbul, 1910) was a Turkish Ottoman composer. Nuri Bey's compositions serve as grand examples of the classical styles.
Nuri Bey took lessons from Hadice Hanım, daughter of Dede Efendi. He apprenticed with Rıza Efendi, sheikh of the Eyüp Hatuniye Lodge, and learned hundreds of ilahis and verses from him. Among Nuri Bey's notable students are Hacı Kirâmi Efendi and neyzen Emin Dede.
"Bolâhenk" is a nickname that means "many harmonies" and "Bey" is a title, like "sir." There were no surnames at the time.
