Sally Alina Ingeborg Salminen (25 April 1906 – 18 July 1976), from 1940 Salminen-Dührkop, was an internationally renowned author from Vargata, the Åland Islands, Finland.

Already as a child she entertained notions of becoming an author, but she considered herself to be too poor and unknowledgeable to succeed as a writer.

While in New York, she wrote during her spare time, and it was here she started writing the manuscript for her first (and most famous) novel, Katrina.

Finland-Swedish publisher Holger Schildts Förlag announced in 1936 a writing contest, for which Salminen submitted her manuscript.

Sally Salminen married Danish painter Johannes Dürhkop in 1940, and relocated to Denmark.
