Garrett James Hardin (April 21, 1915 – September 14, 2003) was an American ecologist and philosopher who warned of the dangers of overpopulation. His exposition of the tragedy of the commons, in a famous 1968 paper in Science, called attention to "the damage that innocent actions by individuals can inflict on the environment". He is also known for Hardin's First Law of Human Ecology: "We can never do merely one thing. Any intrusion into nature has numerous effects, many of which are unpredictable."

Hardin received a B.S. in zoology from the University of Chicago in 1936 and a PhD in microbiology from Stanford University in 1941. Moving to the University of California, Santa Barbara in 1946, he served there as Professor of Human Ecology from 1963 until his (nominal) retirement in 1978. He was among the first members of the Society for General Systems Research.

A major focus of his career, and one to which he returned repeatedly, was the issue of human overpopulation. This led to writings on controversial subjects such as advocating abortion rights, which earned him criticism from the political right, and advocating eugenics by forced sterilization, and strict limits to non-western immigration, which earned him criticism from the political left. In his essays, he also tackled subjects such as conservation and creationism.
