Miles Wedderburn Lampson, 1st Baron Killearn, GCMG, CB, MVO, PC (24 August 1880 – 18 September 1964) was a British diplomat.

[1] The increasing aggressive claims by Italy that the entire Mediterranean and Red Sea areas were in the Italian sphere of influence led to Lampson being instructed that because of "the rise of Italy as a Mediterranean and North African Power that "that the retention of a British garrison on the Suez Canal and at or in the vicinity of Alexandria is essential".

[2] Despite the apparent weaker hand of el-Nahas, the two were about equal as the Foreign Secretary Anthony Eden advised Lampson: "Failure to negotiate a treaty with Egypt, followed by disturbances in that country, their suppression by British forces and the government of Egypt by His Majesty's Government by force and against the will of the Egyptian people, would be represented throughout the Arab Near East possibly as a sign of British bad faith, certainly as a proof of British imperialism pursued at the expense of a weaker Mohametan country".

Lord Killearn died in September 1964, aged 84, and was succeeded in the barony by his son by his first marriage, Graham.

As Graham died without male heirs, the title subsequently passed to Lord Killearn's son from his second marriage, Victor.
