The High Commissioner of the United Kingdom to the Republic of Cameroon is the head of the United Kingdom's diplomatic mission in Cameroon.
In 1960 the French colony of Cameroon became independent as the Republic of Cameroun.
The southern part of British Cameroons merged with it in 1961 to form the Federal Republic of Cameroon.
Cameroon joined the British Commonwealth in 1995: before then the British head of mission was an Ambassador, but now that Cameroon is in the Commonwealth the head of mission is a High Commissioner.
In 2018 the UK government opened a new office in N'Djamena, the capital of Chad, "to support diplomatic, development and defence efforts" but the ambassador is still non-resident (in Cameroon) and the new office does not provide consular assistance.
