Ivan Doig was born at June 27, 1939 in White Sulphur Springs, Montana to a family of homesteaders and ranch hands. After the death of his mother Berneta, on his sixth birthday, he was raised by his father Charles "Charlie" Doig and his grandmother Elizabeth "Bessie" Ringer. After several stints on ranches, they moved to Dupuyer, Pondera County, Montana in the north to herd sheep close to the Rocky Mountain Front.

After his graduation from Valier high school, Doig attended Northwestern University, where he received a bachelor's degree and a master's degree in journalism. He later earned a Ph.D. in American history at the University of Washington, writing his dissertation about John J. McGilvra (1827-1903). He now lives with his wife Carol Doig, née Muller, a university professor of English, in Seattle, Washington.
