Edward Paul Abbey (January 29, 1927 – March 14, 1989) was an American author and essayist noted for his advocacy of environmental issues, criticism of public land policies, and anarchist political views. His best-known works include the novel The Monkey Wrench Gang, which has been cited as an inspiration by radical environmental groups, and the non-fiction work Desert Solitaire. Writer Larry McMurtry referred to Abbey as the "Thoreau of the American West".

Abbey was born in Indiana, Pennsylvania on January 29, 1927 to Mildred Postlewait and Paul Revere Abbey. Mildred was a schoolteacher and a church organist, and gave Abbey an appreciation for classical music and literature. Paul was a socialist, anarchist, and atheist whose views strongly influenced Abbey.

Abbey graduated from high school in Indiana, Pennsylvania in 1945. Eight months before his 18th birthday, when he would be faced with being drafted into the United States military, Abbey decided to explore the American southwest. He travelled by foot, bus, hitchhiking, and freight train hopping. During this trip he fell in love with the desert country of the Four Corners region. Abbey wrote: "[...]crags and pinnacles of naked rock, the dark cores of ancient volcanoes, a vast and silent emptiness smoldering with heat, color, and indecipherable significance, above which floated a small number of pure, clear, hard-edged clouds. For the first time, I felt I was getting close to the West of my deepest imaginings, the place where the tangible and the mythical became the same."
