The Ambassador of the United Kingdom to the Republic of Zimbabwe is the United Kingdom's foremost diplomatic representative in Zimbabwe, and head of the UK's diplomatic mission in Harare.
The High Commission was withdrawn on 12 November 1965, following the Unilateral Declaration of Independence of Rhodesia the previous day.
Initially Zimbabwe was a member of the Commonwealth of Nations so the UK's diplomatic representatives were High Commissioners.
Emmerson Mnagagwa, the President of Zimbabwe has stated that Zimbabwe will seek a return to its membership of the Commonwealth during 2018, following in the footsteps of The Gambia, which returned to its status as a republic in the Commonwealth of Nations on 8 February 2018.
If this does occur, then the UK's head of mission in Zimbabwe will again be a High Commissioner.
