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

In 1935 following demands from the Egyptian prime minister Mostafa el-Nahas for a new Anglo-Egyptian treaty, Lampson embarked on the talks.

[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".

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.
