Derrick Jensen (born December 19, 1960) is an American ecophilosopher, writer, author and environmentalist in the anarcho-primitivist tradition,^[2][3] though he rejects the label "anarchist". Utne Reader named Jensen among "50 Visionaries Who Are Changing the World" in 2008,^[4] and Democracy Now! says that he "has been called the poet-philosopher of the ecology movement".^[5]

Jensen is a critic of the mainstream environmental movement's focus on preserving civilization and technology over preserving the natural world.^[6] He specifically challenges the lifestyle changes and individualistic solutions broadly advocated, considering them drastically inadequate to the global scale of environmental catastrophe.^[7] Instead, he promotes civil disobedience, radical activism, and dismantling infrastructure on a massive level in order to halt what he has called "the murder of the planet".^[6]

Jensen is a founder and leader within Deep Green Resistance.

His and the organization's belief that women-only spaces should exclude trans women has led to accusations of transphobia.^[8][6]

Jensen lives in Crescent City, California.^[1]
