Ditlevine Feddersen (née Collett; 19 July 1727 – 18 November 1803) was a Norwegian poet, translator and culture personality.
She was one of eleven children of the wealthy merchant Peter Collett (1694–1740) and Anna Cathrine Rosenberg (1699–1747).
[2][3] When her parents died, she lived together with her younger sister, Mathia, and their aunt until her marriage.
She was the muse of the poet Christian Braunmann Tullin, and in turn wrote her own poems which were influenced by him.
[5] She wrote poems during great events in the city society life, such as Til Digteren Tullin paa egne og flere Damers Vegne, da han havde skrevet sin Majdag (1758).
