Lucie Dreyfus-Hadamard (23 August 1869 – 14 December 1945) was the wife of Alfred Dreyfus.

Lucie worked to convince French authorities to exonerate her husband.

During the Second World War, Lucie lived in a convent to avoid becoming a victim of the Holocaust; a granddaughter, Madeleine Lévy, was killed in Auschwitz.

In The Life of Emile Zola (1937), Lucie was played by Gale Sondergaard.

In An Officer and a Spy (2020; French: J'Accuse), Lucie was played by Swan Starosta.
