The prize, established in 1992 to honor work by a mid-career poet, was given for her book "Modern Life."
Matthew Dickman, a Portland, Ore., writer, was selected by the Claremont judges to receive the $10,000 Kate Tufts Discovery Award for his book "All-American Poem."
Harvey is the second Brooklyn poet in a row to win the $100,000 award, following the selection last year of Tom Sleigh.
Harvey's other books are "Sad Little Breathing Machine" (2004) and "Pity the Bathtub Its Forced Embrace of the Human Form" (2000).
"Modern Life," published by Graywolf Press in 2007, was a finalist for the 2008 National Book Critics Circle Award for Poetry.
The awards will be presented April 23 at the Colburn School of Music in downtown Los Angeles. The event is free and open to the public.
