Alien Nation: Common Sense About America's Immigration Disaster is a 1995 national bestseller book by paleoconservative British American journalist Peter Brimelow. It criticizes US immigration policy after 1965 from a conservative perspective. It highlights differences in post-1965 immigration policy with previous periods of immigration along with detailed responses to immigration advocates’ arguments.
In June 2007, VDARE, a controversial website founded by Brimelow that focuses on immigration restriction, made the book available as a free PDF download. It is released under a Creative Commons license.
