Parliament of Whores: A Lone Humorist Attempts to Explain the Entire U.S. Government is an international best-selling political humor book by P. J. O'Rourke published by Atlantic Monthly Press in 1991.

It is a scathing critique of the American system of governance from a libertarian perspective.

Time Magazine called it "a riotously funny and perceptive indictment of America's political system".

[3] The New York Times called it "a funnily savage attack on the political authorities of the United States".

[4] In a piece about its 1992 paperback release, USA Today described it as "the anthem of this political year".
