This is a list of Greek princesses by marriage from the accession of Geórgios I to the throne of the Kingdom of Greece in 1863. Individuals holding the title of princess would usually also be styled "Her Royal Highness" (HRH).
Elizabeth II, Queen of the United Kingdom, MarÃÂna Kárella and Irina Aleksandrovna Ovtchinnikova, while meeting most of the requirements, are not classed princesses by marriage of Greece, because Prince FÃÂlippos, husband of Elizabeth II, renounced his Greek (and Danish) titles, Prince MichaÃÂll had a morganatic marriage, and Prince Pétros lost his succession rights upon his marriage.
