The Ambassador of the United Kingdom to Italy is the United Kingdom's foremost diplomatic representative in the Italian Republic, and head of the UK's diplomatic mission in Italy. The official title is His Britannic Majesty's Ambassador to the Italian Republic (until 1946, the Kingdom of Italy). The first British mission to the united Italy was a legation located in Turin, taking over the now defunct mission to the Kingdom of Sardinia; it moved to Rome in 1871. The mission was upgraded to a full embassy in 1876.
The office incorporates that of Ambassador of the United Kingdom to the Most Serene Republic of San Marino.
