List of diplomats of the United Kingdom to Iran

The ambassador of the United Kingdom to Iran is the United Kingdom's foremost diplomatic representative in the Islamic Republic of Iran, and in charge of the UK's diplomatic mission in Iran. The official title is His Majesty's Ambassador to the Islamic Republic of Iran.

Although Britain and Iran (originally Persia) did not enter into formal diplomatic relations until 1807, British and Iranians had been in informal contact since the early 17th century when the East India Company developed trade links with the Persian kingdom. Initially, diplomatic missions comprised a legation until they were promoted to embassy status in 1943.

At various times in history during crises or disputes, Britain has had no diplomatic presence in the country, and has either relied on other nations as protecting powers, or has had a non-resident diplomat.
