Jacques Lanzmann (4 May 1927 – 21 June 2006) was a French journalist, writer and lyricist. He is best known as a novelist and for his songwriting partnership with Jacques Dutronc.

Lanzmann spent the early part of his life in Auvergne. His parents, Paulette (Grobermann) and Armand Lanzmann, divorced shortly before World War II and, at the age of 12, he became a farmhand. Lanzmann was Jewish and, following the Battle of France, he, his mother and his siblings, pretended to be Moroccan Arabs in order to escape persecution by the Vichy regime.
