The ambassador of the United Kingdom to Russia (Russian: ÃÂÃÂøÃÂðýÃÂúøù ÃÂþÃÂþû ò àþÃÂÃÂøø) is the United Kingdom's foremost diplomatic representative in the Russian Federation and head of the UK's diplomatic mission in Russia. The official title is His Britannic Majesty's Ambassador to the Russian Federation.
Between 1844 and 1860 the status of the head of mission in Saint Petersburg was reduced from Ambassador to Envoy Extraordinary and Plenipotentiary. The capital of Russia, and later of the Soviet Union (from 1922 to 1991), moved to Moscow in 1918.
For the envoys to Russia from the Court of St James's before the creation of the United Kingdom of Great Britain and Ireland in 1801, see List of ambassadors of the Kingdom of England to Russia (for the period until 1707) and List of ambassadors of Great Britain to Russia (for the years 1707 to 1800).
