Princess Sophie Marie of Liechtenstein, Countess Esterházy von Galántha (Vienna, 5 September 1798 – Vienna, 27 June 1869), was an Austrian courtier. As the daughter of Johann I Joseph, Prince of Liechtenstein, she was a princess of Liechtenstein by birth and grew up at the princely court. Born and raised in Vienna, she was selected to serve in the Austrian imperial court. She served as Oberhofmeisterin (mistress of the Robes) to Empress Elisabeth of Austria from 1854 to 1862.
She was disliked by the Empress, as she was a friend and a confidante of the Empress' mother-in-law, Princess Sophie of Bavaria, and suspected to be her spy. She was also described as very strict, and her attitude toward Elisabeth was compared to a governess. She was replaced by Pauline von Königsegg. She has been portrayed in numerous books about Elisabeth.
