The modern Union-Bulletin can trace its origins to the Washington Statesman, the city's first newspaper, founded in September 1861. The Statesman began publishing weekly editions on November 29, 1862, using an old printing press acquired from the Oregon Statesman in Salem. The weekly newspaper was renamed the Walla Walla Statesman in 1864 and began offering daily editions in 1878. The Walla Walla Union was founded in 1868 as a Republican Party newspaper, to counter the Statesman's Democratic leanings, and began publishing in April 1869 as a weekly and in 1881 as a daily. The Union was merged with the Statesman in 1907, coming under the common ownership of Washington Printing and Book Publishing Company.
The Walla Walla Bulletin began publication on February 12, 1906, becoming the third largest newspaper in the Walla Walla region. The Bulletin and Union were merged into the Union-Bulletin by owner John G. Kelly in 1934, who had acquired the Bulletin in 1910. The Union-Bulletin was operated as an independent newspaper until it was acquired by The Seattle Times Company on October 1, 1971.
Since May 1, 2015, Brian Hunt has been the publisher of the Union-Bulletin.
