Douglas Krueger is an American philosopher, academic and author. He is best known as a proponent of atheism and an advocate of skepticism regarding supernatural and paranormal claims. Krueger has been a featured speaker at numerous atheist and humanist conventions and gatherings and is a co-founder of the Fayetteville Freethinkers, a secular humanist organization in Fayetteville, Arkansas. His book, What is Atheism: A Short Introduction, is a concise and hard-hitting—though some have claimed unfairly biased—critique of religious belief, especially Christianity.
