Jill Bialosky (born in Cleveland, Ohio) is an American poet, book editor, and novelist.
She studied at Ohio University and received an M.A. in Writing Seminars at Johns Hopkins University, as well as an M.F.A. from the University of Iowa. She is the author of four poetry collections published by Alfred A. Knopf. Her poems have appeared in journals such as The Paris Review, American Poetry Review, The Kenyon Review, The New Yorker, and The Atlantic Monthly. She is also the author of two novels, House Under Snow and The Life Room, and is an editor at W. W. Norton. Bialosky's memoir of her sister Kim's 1990 suicide, A History of a Suicide: My Sister's Unfinished Life, was published in 2011. Insightful and maturely crafted, the memoir probes "the possibility of a genetic susceptibility to suicide, and examines the question of how any young person can really know he or she wants to die." On May 20, 2014 Jill Bialosky was honored by the Poetry Society of America for her distinguished contribution to the field of poetry. 
Bialosky lives in New York City with her husband and son.
