German: Prinzessin Cecilia von Griechenland und Dänemark, member of the house of Schleswig-Holstein-Sonderburg-Glücksburg.

Cecilie was the third child and daughter of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg. On 2 February 1931 at Darmstadt Cecilie married George Donatus, Hereditary Grand Duke of Hesse and by Rhine. They had four children. In October 1937, Cecilie's father-in-law Grand Duke Ernst Ludwig of Hesse died. A few weeks after the funeral, her brother-in-law Prince Ludwig was due to be married to the Hon. Margaret Campbell-Geddes in London.

On 16 November 1937, Georg Donatus, Cecilie, their two young sons, along with Georg's mother Grand Duchess Eleonore, left Darmstadt for London. The aeroplane hit a factory chimney near Ostend and crashed into flames, killing all those on board. Cecilie was eight months pregnant with her fourth child at the time of the crash, and the remains of the fetus were found in the wreckage, indicating that Cecilie had gone into labour or suffered sufficient bodily trauma to result in birth.
