Naomi Rebekah Wolf (born 1962) is an American feminist author, journalist, and conspiracy theorist.

After the 1991 publication of her first book, The Beauty Myth, Wolf became a leading spokeswoman of what has been called the third wave of the feminist movement. Feminists including Gloria Steinem and Betty Friedan praised her work. Others, including Camille Paglia, criticized it. In the 1990s, she was a political advisor to the presidential campaigns of Bill Clinton and Al Gore.

Wolf's later books include the bestseller The End of America in 2007 and Vagina: A New Biography. Critics have challenged the quality and accuracy of her books' scholarship; her serious misreading of court records for Outrages (2019) led to its U.S. publication being canceled. Wolf's career in journalism has included topics such as abortion and the Occupy Wall Street movement in articles for media outlets such as The Nation, The New Republic, The Guardian, and The Huffington Post.

Since around 2014, Wolf has been described by journalists and media outlets as a conspiracy theorist. She has been criticized for promoting misinformation on topics such as beheadings carried out by ISIS, the Western African Ebola virus epidemic, and Edward Snowden.

Wolf has objected to COVID-19 lockdowns and criticized COVID-19 vaccines. In June 2021, her Twitter account was suspended for posting anti-vaccine misinformation.
