Dan O'Neill (Daniel T. O'Neill) is an Alaskan writer. He is the author of three books of literary nonfiction: The Firecracker Boys (1994), an exposé of the 1958 plan (called Project Chariot) to excavate a harbor in Alaska using nuclear devices; The Last Giant of Beringia (2004), detailing the history of scientific thought about the Bering land bridge and geologist David Hopkin's central role in establishing current theory; and A Land Gone Lonesome (2006), an exploration of the history, prehistory, and culture of the upper Yukon River and its frontier inhabitants. His nonfiction children's book Stubborn Gal (2015) tells the true story of a young woman who wins a 60-mile sled dog race, despite having no experience in the sport.

O'Neill was born in 1950 in San Francisco, California. His parents were San Francisco natives; his four grandparents were born in Ireland.

He attended St. Mary's College of California, and graduated from U.C. Berkeley in 1972. That same year, he hitchhiked to Alaska; returning to San Francisco, he worked for two years as a draftsman, land use planner, and environmental planner for Pacific Gas & Electric Company.

In 1975 he moved to Alaska and settled in Fairbanks, where he spent his first winter as caretaker of Chena Hot Springs (now Chena Hot Springs Resort).^[1] His early adventures included mushing his own dog team 800 miles to Nome, Alaska,^[1] following the trail of the 1925 Nome Serum Run. For a few years he was a self-employed log cabin builder.

From 1984 to 1994, O'Neill was a research associate in the Oral History Program^[1] at the University of Alaska Fairbanks. He conducted more than 100 tape-recorded interviews of notable Alaskans, including Alaska Native elders, former Alaska Governor Steve Cowper and his cabinet members, the late Alaska Poet Laureate John Haines, university presidents and chancellors, scientists, business leaders, fishermen/women, bush pilots, steamboat and railroad men, and many others.^[2]

In addition to oral histories, O'Neill produced radio and television programming and videos on topics in history, science, and politics.^[3]

O'Neill turned to writing full time in 1995, but his experience as an oral historian continued to inform and inspire much of his work. For instance, his interviews concerning the Yukon-Charley Rivers National Preserve (digitized at Project Jukebox)^[4] formed the basis of his book A Land Gone Lonesome, which was chosen a 2006 "Editor's Choice" by The New York Times Book Review.^[5]

In addition to his books, O'Neill has written book chapters, magazine articles, and scholarly articles and reviews. He was an opinion columnist for the Fairbanks Daily News-Miner from 1998 to 2002.^[1]

O'Neill and Sarah D. Campbell, a biologist and engineer, were married in 1977. They have one child and three grandchildren.
