The Portland Daily Bulletin was a newspaper launched in 1870 in Portland, Oregon, United States. Railroad promoter Ben Holladay launched the newspaper, one of several efforts to challenge The Oregonian's position as Portland's dominant newspaper, as part of his effort to promote his railroad interests. Holladay appointed James O'Meara as editor Harvey W. Scott, renowned longtime editor of The Oregonian, became editor of the Bulletin in 1873. Scott was succeeded by T. B. Odeneal. Holladay ceased publication in 1875, claiming that he had lost nearly $200,000 on it.
