Springfield's largest local newspaper is The Republican. It was formerly the Springfield Union-News & Sunday Republican. Smaller papers such as The Reminder and the Valley Advocate also serve Greater Springfield. Other newspapers include Predvestnik (a Russian language newspaper) and El Pueblo Latino, which serves the Hispanic community, and Unity First which serves the African-American community.

Established by Samuel Bowles (II) in 1824 as a rural weekly, it was converted into a daily in 1844 by Samuel Bowles (III). From the beginning it had a focus on local news. As rapidly as possible its news-gathering was extended until within a few years its columns contained departments of items from every town and hamlet along the Connecticut Valley, as well as from Springfield. It achieved national renown in the nineteenth century under the tenure of Samuel Bowles (III), a legacy that was passed to his son, Samuel Bowles (IV).

Bowles (III) believed that the newspaper should be a power in the moral, religious, and literary, as well as the political life of the community, and he tried to make his paper fulfill those functions. With the aid of J. G. Holland and others who joined the staff the paper attained excellent literary quality and a high moral tone. Its opinions soon reached all New England, and after the formation of the Republican party they extended far beyond the limits of any section.

During the controversies affecting slavery and resulting in the American Civil War, Bowles supported, in general, the Whig and Republican parties, but in the period of Reconstruction under President Ulysses S. Grant, his paper represented anti-administration or Liberal Republican opinions, while in the disputed election of 1876 it favored the claims of Samuel J. Tilden, and subsequently became independent in politics.

During Bowles' lifetime, and subsequently, the Republican office was a sort of school for young journalists, especially in the matter of pungency and conciseness of style, one of his maxims being: "put it all in the first paragraph".

Bowles was an acquaintance of Emily Dickinson, and he published a handful of the very few poems by the poet printed in her lifetime, including "A narrow fellow in the grass" and "Safe in their alabaster chambers."

Bowles was succeeded as publisher and editor-in-chief of the Republican by his son Samuel Bowles (b. 1851).

The paper closed after a long strike in 1947 but restarted circulation in the 1960s. Wayne E. Phaneuf is currently the executive editor of the paper. Former executive editor Larry McDermott is currently the newspaper's publisher.

The newspaper was formerly known as The Springfield Union News & Sunday Republican. The name change occurred around year 2000.
