Benno Vigny (real name Benoit Philippe Weinfeld; 28 October 1889 – 31 October 1965) was a French-German screenwriter, novelist, songwriter, and librettist. Born into a Jewish family in France and raised in Vienna, Austria, Vigny's first significant work as a writer was the libretto for Robert Winterberg's operetta Fasching in Paris (1910). After serving in the French Army during World War I, he began a relationship with Marie-Louise Caussat, the mother of French songwriter Charles Trenet. She divorced her first husband in 1920, and married Vigny in 1922.
