The Honourable George Edward Adeane CVO (4 October 1939 – 20 May 2015) was an English barrister and royal advisor who served as Private Secretary to the Prince of Wales from 1979 to 1985.

As a barrister, he defended Time Out magazine, owned by Playboy Publications, Inc., in 1973, when they had accused Fiona Lewis, an actress, of being involved with South American revolutionaries.

The following year, he represented The Spectator magazine, which had libelled publishers Jonathan Cape, suggesting they were in financial difficulties, and won a similar outcome.

In 1975, he more successfully represented Marcia, Lady Falkender, who was falsely accused of forging her boss's signature, former Prime Minister Harold Wilson.

In 1977, Adeane represented Marlene Dietrich in a libel case brought by producer Alexander Cohen for breach of contract as a disreputable performer.
