This is a list of Greek princesses by marriage from the accession of George 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, Marina Karella and Irina Aleksandrovna Ovtchinnikova, while meeting most of the requirements, are not classed princesses by marriage of Greece, because Prince Philip, husband of Elizabeth II, renounced his Greek (and Danish) titles, Prince Michael had a morganatic marriage, and Prince Peter lost his succession rights upon his marriage.
