Maria "Marfa" Feodorovna Nagaya (Russian: Мария Фёдоровна Нагая; February 8, 1553 - June 28 1608, Moscow) was a Russian tsaritsa and last and sixth (possibly eighth) wife of Ivan the Terrible.She was mother of Tsarevich Dmitry of Uglich .
Daughter of the okolnichy Fyodor Fyodorovich Nagoy-Fedets. According to historians and genealogists N.V. Myatlev (1872-1929) and Anat. G. Gryaznoy, the daughter or sister of Prince Vasily Semenovich Funikov- Kemsky was the wife of F.F. Nagoy , and therefore the mother of his children, for which Fyodor Fyodorovich received part of the Zvenigorod patrimony of the princes Funikov- Kemsky as a dowry.
Her uncle was the Russian ambassador to the Crimean Khanate , a diplomat and close confidant of the tsar, Afanasy Nagoy, which apparently contributed to the marriage.
