Her senior dresser Angela Kelly, revealed in a book that Her Majesty made the change this year in response to changing societal attitudes.
At least one coat in her wardrobe has been altered, while any new outfits designed for the Queen will use fake fur instead.
Animal rights groups have applauded the move by the monarch with Humane Society International suggesting it sends a "powerful message" that fur's out of fashion.
The news comes after a number of designer fashion brands including Gucci and Prada made similar announcements to go fur-free.
Samantha Chandler from Christian animal rights charity, Anglican Society for Welfare of Animals told Premier she welcomed the decision.
"We think it's fantastic," she said. "It was always a bit of a shame that our Queen, as head of the Church of England, continued to wear fur."
"I think it's definitely out of fashion now, people who wear fur are seen as not on trend, I don't think young people as a general rule would be seen dead in fur coats.
Chandler went on to say that the decision speaks of Her Majesty's character and investment in her country: "She is a very thoughtful and well-read woman. She certainly does keep an eye on what is going on in the media in the news, particularly public opinion of her subjects and her citizens.
"Perhaps it has caused her to question her choices and whether what she is doing is humane, ethical and right for this country where we are in 2019."
Chandler, who is also a vegan, says she thinks wearing fur is unethical and at odds with her Christian values: "Animals are created beings. They are created by God. I don't think they're here for us to use.
"I think they are here for us to enjoy - to enrich the world in which we live, to add to the beauty of creation and the preciousness of creation."
Chandler says wearing fur is exploitative because it's a luxury item that animals are poorly treated to produce, with many contained in small cages and raised poorly for their pelts.
"You've only got to look at the Beatitudes. The one that always stands out for me is 'Blessed are the merciful' I think we are called to be merciful, to be humane and to consider the lives of others.
"Animals are sentient beings with feelings and emotions that has been proved by science many times, and I think to knowingly cause great suffering to what are really wild animals for the sake of a fashion item can never be right," she added.
