The Ambassador Extraordinary and Plenipotentiary of the Russian Federation to the United Kingdom of Great Britain and Northern Ireland, or formally the Ambassador of the Russian Federation to the Court of St James's, is the official representative of the President and the Government of the Russian Federation to the Monarch and the Government of the United Kingdom.

[1] The post of ambassador to the United Kingdom is currently held by Andrey Kelin, incumbent since 5 November 2019.

[2] The United Kingdom established diplomatic relations with the Soviet Union in 1924.

However, King George V was still upset over the execution of the Romanov family and refused to receive the Soviet ambassador.

In a breach of diplomatic protocol, he dispatched the Prince of Wales to accept the Soviet ambassador's credentials.
