Embassy of the United Kingdom, Tehran

The Embassy of the United Kingdom in Tehran is the United Kingdom's diplomatic mission to the Islamic Republic of Iran. It is located at 172 Ferdowsi Avenue in Tehran.

Following the 2011 attack on the Embassy and the expulsion of the British ambassador by Iran, Britain reduced its diplomatic relations with Iran to "the lowest possible level" and closed its embassy. However, following the election of President Hassan Rouhani, relations improved and both countries appointed non-resident charge d'affaires to conduct bilateral relations between London and Tehran. The embassy reopened in August 2015 and relations were upgraded in 2016, with relations now conducted once again by an ambassador. The current ambassador to Iran is Simon Shercliff.
