Anna Marly (Russian: Анна Юрьевна Смирнова-Марли, Anna Yurievna Smirnova-Marli) (30 October 1917 – 15 February 2006), born Anna Yurievna Betulinskaya, was a Russian-born French singer-songwriter and guitarist. Born into a wealthy Russian noble family, Marly came to France very young, just after her father was killed in the aftermath of the October Revolution.

She is best remembered as the composer of the "Chant des Partisans", a song that was used as the unofficial anthem of the Free French Forces during World War II; the popularity of the "Chant des Partisans" was such that it was proposed as a new national anthem after the conclusion of the war. She also wrote "La Complainte du Partisan" (known in English as "The Partisan"), which was later famously covered by Leonard Cohen and Joan Baez.
