The William E. Colby Military Writers' Award was established in 1999 by the William E. Colby Military Writers' Symposium at Norwich University in Vermont in order to recognize "a first work of fiction or non-fiction that has made a major contribution to the understanding of intelligence operations, military history, or international affairs." It is named in honor of William Egan Colby.^[1] As of 2021, Alex Kershaw is the chair of its selection committee.^[2]

The Colby Circle was co-founded by writers Carlo D'Este and W.E.B. Griffin. The award honorarium is currently administered by the Tawani Foundation in Chicago, and presented at the annual William E. Colby Military Writers' Symposium hosted by Norwich University.
