The Marion Daily Star is a newspaper in Marion, Ohio, originally owned and published by Warren G. Harding and Florence Kling Harding. Founded as the Daily Pebble, the format of the small daily grew and became the Daily Marion Star. When Harding acquired the newspaper in the 1880's it was struggling. The dubious financial position of the Marion Daily Star improved following the marriage of Harding to Florence Kling who promptly set about to straighten out the accounting and increase circulation.

Following the death of the Hardings and the sale of the Harding Publishing Company, the paper was owned by various entities. For a number of years, the paper was part of the Thompson Newspaper chain based in Canada, who changed the name briefly to "The Star". Again known as The Marion Star, the paper is owned and operated by the Gannett Newspaper organization of Rosslyn Virginia. Under Gannett, editorial and business offices are mantained in Marion, while printing operations have been moved to a regional press house in Mansfield, Ohio.
