Marō Douka (Greek: Μάρω Δούκα) is a Greek novelist. She belongs to the so-called "Genia tou 70," which is a literary term referring to Greek authors who began publishing their work during the 1970s; her debut work, Η Πηγάδα (The Cauldron), based on her imprisonment in 1967 by the Military Junta, was published in 1974, just a few months after the fall of the military junta of 1967–74.

She was awarded the Nikos Kazantzakis Prize of the Municipality of Heraklion for Η αρχαία σκουριά (Fool's Gold) and the Greek State Prize for Literature for Η πλωτή πόλη (The Floating City), declining the latter award. Αθώοι και φταίχτες (The Innocent and the Guilty) was awarded the Balkanika Prize for Literature, the Kostas and Eleni Ouranis Prize of the Academy of Athens and the Cavafy prize. She has also been awarded the N. Themelis prize for her recent novel Έλα να πούμε ψέματα (Come, Let Us Tell Lies).

She is a founding member of the Hellenic Authors' Society. At the 2014 local elections, she was elected to the City Council of Athens on the "Anoihti Poli" Syriza ticket, led by Gabriel Sakellaridis.
