Gordon Dahlquist is an American playwright and novelist. A native of the Pacific Northwest, Dahlquist has lived and worked in New York City since 1988. His plays, which include Messalina and Delirium Palace (both Garland Playwriting Award winners), have been performed in New York and Los Angeles. He is a graduate of Reed College and Columbia University's School of the Arts and an alumnus of New Dramatists.

Dahlquist's debut novel, The Glass Books of the Dream Eaters, a hybrid of fantasy and science fiction set in a period similar to the Victorian era, was published on August 1, 2006, to notable critical acclaim. Despite the success in terms of critical reception, sales were disappointing, and it reportedly lost its publisher, Bantam, approximately $851,500. The sequel, The Dark Volume, was published in the UK by Penguin on May 1, 2008, and on March 24, 2009, in the United States. A third volume, The Chemickal Marriage, was published in July 2012.

Besides his novels, Dahlquist published a young adult novel, The Different Girl, in 2013. In 2015, he received the James Tait Black Prize for his play Tomorrow Come Today.
