Edward William Macleay Grigg, 1st Baron Altrincham, KCMG, KCVO, DSO, MC, PC (8 September 1879 – 1 December 1955) was a British colonial administrator and politician.

Grigg was the son of Henry Bidewell Grigg, CIE, a member of the Indian Civil Service, sometime Political Resident of Travancore, and Elizabeth Louisa, née Thomson, whose parents were the Australian politician and administrator Sir Edward Deas Thomson and his wife, Anna Maria, daughter of General Sir Richard Bourke, Governor of New South Wales from 1831 to 1837.

[8] Serving in France, he distinguished himself in combat before his transfer to the staff as a GSO 3 on 4 February 1916,[9] briefly relinquishing his temporary rank of captain with effect from 27 January,[10] and resuming it from 15 April.

Grigg became devoted to Lloyd George and developed a deep respect for the "Welsh Wizard" that subsequently limited his political career.

However, he opposed consideration of the colony's development into a multi-racial state and believed that the native African population was ill-prepared for managing the government.

However, Grigg never openly challenged the policy of appeasement that was advanced by the governments of Stanley Baldwin and Neville Chamberlain and kept his criticisms private.

He declined Winston Churchill's invitation to become First Commissioner of Works, as it was dependent upon acceptance of a peerage, and Grigg did not return to government until 21 November 1944 when he was selected as Minister-Resident for the Middle East as successor to Lord Moyne, who had been assassinated two weeks earlier.

[15] In the aftermath of the Conservative caretaker government's defeat at the 1945 general election, Grigg was raised to the peerage as Baron Altrincham, of Tormarton in the County of Gloucester, which ended his political career.
