Cleveland Amory (September 2, 1917 – October 14, 1998) was an American author, reporter and commentator and animal-rights activist.
He originally was known for writing a series of popular books poking fun at the pretensions and customs of society, starting with The Proper Bostonians in 1947.
From the 1950s through the 1990s, he had a long career as a reporter and writer for national magazines, and as a television and radio commentator.
In the late 1980s and 1990s, he was best known for his bestselling books about his adopted cat, Polar Bear, starting with The Cat Who Came for Christmas (1987).
Amory devoted much of his life to promoting animal rights, particularly protection of animals from hunting and vivisection; the executive director of the Humane Society of the United States described Amory as "the founding father of the modern animal protection movement."
