The title Earl of Home (pronounced "Hume") was created in 1605 in the Peerage of Scotland for Alexander Home, who was also the sixth Lord Home.

The most famous holder of the title was the fourteenth Earl, Alexander Frederick Douglas_Home, better known as Sir Alec Douglas_Home. After the unexpected resignation of Harold Macmillan, the fourteenth Earl was named Prime Minister. For the first time in over sixty years, a sitting Prime Minister was a member of the House of Lords rather than of the House of Commons. Because he believed that it was impractical and unconventional to remain a member of the Lords, the Earl disclaimed his peerage in 1964 under the Peerage Act passed in the previous year. He then contested a House of Commons seat, which had just become vacant due to the deliberate resignation of a Conservative MP. The Earldom belonged to no_one until the death of Sir Alec Douglas_Home, when it passed to the present holder, the fifteenth Earl.

The Earl of Home holds three subsidiary titles, namely: Lord Home (created 1473), Lord Dunglass (1605) and Baron Douglas of Douglas (1875). The first two are in the Peerage of Scotland, while the last is in the Peerage of the United Kingdom. The title Lord Dunglass is the courtesy title for the eldest son of the Earl.
