Alexander Frederick Douglas-Home, Baron Home of the Hirsel, KT, PC (/ˈhjuːm/ (audio speaker iconlisten); 2 July 1903 – 9 October 1995) was Prime Minister of the United Kingdom from 1963 to 1964. He was better known as Alec Douglas-Home.

Home was a Member of Parliament and a junior official (a Parliamentary Private Secretary) when Neville Chamberlain went to Munich to meet Adolf Hitler in 1938. He was present at the main meetings between Hitler and Chamberlain. Later in life, he was appointed by Harold Macmillan as Foreign Secretary in 1960–1963, and again in Edward Heath's government from 1970–1974.

Home's name and title changed a few times during his life. Born as Alexander Frederick Douglas-Home, he became Lord Dunglass when his father became the Earl of Home. Dunglass is a junior title, that is, a lower title which is held by the eldest son. When his father died Alec became the 14th Earl of Home. He also became Baron Douglas in the peerage of the United Kingdom (that was also a junior title).
