Tim Kasser (August 1, 1966) is an American psychologist and book author known for his work on materialism and well-being.
Kasser received his Ph.D.
in Psychology from the University of Rochester in 1994, and after one additional year of teaching at Montana State University, he accepted a position at Knox College in Galesburg, Illinois, where he was a professor of psychology.
He retired from Knox in 2019 and was named Emeritus Professor.
He has authored over 120 scientific articles and book chapters on materialism, values, goals, well-being, and environmental sustainability, among other topics.
His first book, The High Price of Materialism, was published in 2002 (ISBN 978-0262611978); his second book (co-edited with Allen D.

In 2009 he co-authored a book (with Tom Crompton) Meeting Environmental Challenges: The Role of Human Identity.
In 2013 he wrote Lucy in the Mind of Lennon, a psychological biography that explores the meaning of John Lennon's song, Lucy in the Sky with Diamonds.
Most recently, in 2018, he collaborated with the cartoonist Larry Gonick on HyperCapitalism: The modern economy, its values, and how to change them.
Since the early 2000s, Kasser has consulted with activist and civil-society organizations who work against the commercialization of children and who work towards a more inwardly rich lifestyle than what is offered by consumerism.
He lives with his wife, two sons, and assorted animals, including a donkey named Earl, in the western Illinois countryside.
