Daniel Clement Dennett III (March 28, 1942 – April 19, 2024) was an American philosopher and cognitive scientist. His research centered on the philosophy of mind, the philosophy of science, and the philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.

Dennett is widely regarded as a proponent of materialism in the philosophy of mind. He argues that mental states, including consciousness, are entirely the result of physical processes in the brain.

He was the co-director of the Center for Cognitive Studies and the Austin B. Fletcher Professor of Philosophy at Tufts University in Massachusetts. Dennett was a member of the editorial board for The Rutherford Journal and a co-founder of The Clergy Project.

As in Consciousness Explained, Dennett advertises the controversial nature of his views extensively in advance. He expects hostility from those who fear that a skeptical analysis of freedom will undermine people's belief in the reality of moral considerations; he likens himself to an interfering crow who insists on telling Dumbo he doesn't really need the feather he believes is allowing him to fly.
