Nelly Enger (1873-1953) was a Norwegian pianist, composer and music teacher.

She studied music with Elise Wiel, Astrid Onarheim and Agathe Backer-Grøndahl, and studied composition with Otto Winter-Hjelm.

She worked as a piano teacher in Kristiania (now Oslo) until she became ill in 1920, when she moved back to the farm where she grew up.
