The ambassador of the United Kingdom to Estonia is the United Kingdom's foremost diplomatic representative in the Republic of Estonia, and head of the UK's diplomatic mission in Tallinn. The official title is His Britannic Majesty's Ambassador to the Republic of Estonia.

The United Kingdom first recognised Estonian independence during the Russian Civil War, and the two countries exchanged envoys for over twenty years. The United Kingdom refused to recognise the Soviet Union's unilateral annexation of Estonia in 1940, and the de facto non-independence caused the UK to close its mission and sever diplomatic ties with Estonia as a result. In 1991, upon restoration of de facto independence, the United Kingdom reestablished diplomatic links with Estonia, and the two countries resumed their exchange of ambassadors.
