Edward Sebastian Grigg, 4th Baron Altrincham (born 18 December 1965), is a British hereditary peer and Conservative member of the House of Lords.

Grigg unsuccessfully stood for the House of Commons for the Heywood and Middleton constituency in Manchester in 1997,[7] aged 31, while working as a junior banker at Goldman Sachs.

He wrote the afterword to Black Rainbow describing her depression and his experience of being a Parliamentary candidate while working for Goldman Sachs and this was subsequently republished in the Evening Standard in 2014[8] including these lines:This is the story of how we muddled through together.

[9] He made his maiden speech on 13 October 2021, talking about his wife's depression, working as a banker, standing for Parliament in 1997 and his family's history.

He had been Governor of Kenya, Member of Parliament for the Altrincham constituency in Cheshire from 1933 to 1945 and then British Government Minister-Resident for the Middle East based in Cairo in 1944 following the assassination of Lord Moyne.

On his death in 1955, the title passed to the writer and journalist John Grigg whose life as Lord Altrincham was partly recreated in Season 2 of The Crown.
