The Ambassador of the United Kingdom to Lebanon is the United Kingdom's foremost diplomatic representative in the Lebanese Republic, and head of the UK's diplomatic mission in Beirut.

The first two British envoys were appointed during World War II^[1] to both Lebanon and Syria. Since 1923 both countries had been under French mandate from the League of Nations. During the war, however, France was partly occupied by Germany and French troops in Lebanon and Syria were loyal to the Vichy French government, so the Allies invaded and occupied Lebanon and Syria in 1941. Both countries became independent after the war.
