Ceclava Czapska (Cécile Czapska) (Bucharest 2 January 1899 – 1 December 1970) was a Romanov impostor who claimed to be the Grand Duchess Maria, daughter of Tsar Nicholas II, the last autocratic ruler of Imperial Russia, and his wife Tsarina Alexandra.

She was the daughter of Polish nobleman, Bolesław Czapski and Raja Ludmilla Tchaplina.

[1] On 20 January 1919, she and Prince Nikolai Alexandrovich Dolgoruky (1898-1970), called 'di Fonz,' were married in Romania.

The remains of all the Romanovs have been found and identified via DNA testing disproving her claim.
