The Embassy of Vietnam in Moscow is the diplomatic mission of the Socialist Republic of Vietnam to the Russian Federation. The chancery is located at 13 Bolshaya Pirogovskaya Street in the Khamovniki District of Moscow.
The embassy occupies a former Mazurin orphanage building, privately funded by the estate of the late French-born Marie Charbonneau who was a long-term unmarried partner of Nikolay Mazurin. Charbonneau bequested 200,000 roubles in cash and 80,000 in stock to establish an orphanage to be named after Mazurin. The City Hall provided land on the north-western corner of then emerging Devichye Pole medical campus; the building, completed in 1895, became the first solo project by a 30-year-old architect Illarion Ivanov-Schitz.
