Aspasia Manou (Greek: Ασπασία Μάνου; 4 September 1896 – 7 August 1972) was a Greek aristocrat who became the wife of Alexander I, King of Greece. Due to the controversy over her marriage, she was styled Madame Manou instead of "Queen Aspasia", until recognized as Princess Aspasia of Greece and Denmark after Alexander's death and the restoration of King Constantine I, on 10 September 1922. Through her marriage, she and her descendants were the only ethnically Greek members of the Greek royal family, which originated in Denmark.
