The Louisiana Signal was a campaign paper published on behalf of John Bell and Edward Everett, candidates of the Constitutional Union Party for President and Vice President, respectively, in the 1860 election.

Beginning on Wednesday, August 29, 1860, in New Orleans, The Louisiana Signal was under the editorial control of W. R. Adams, formerly editor of the Crescent. It was published three times a week - on Thursday, Saturday and Tuesday - beginning with issue 3 of 29 issues. The last issue of Monday, November 5, the day before Election Day, was a repeat of Saturday, November 3.

John Bell, a Senator from Tennessee, was first elected to Congress at age 31 in 1827. He was the only one of the four 1860 Presidential candidates who ever owned slaves. He believed that slavery was right morally, politically and religiously, and that it "civilized and Christianized the negro."

Bell felt that he was competing primarily against John C. Breckenridge, candidate of the Southern Democratic party, which he accused of supporting "The Red Flag of Disunion" and "Conspiracy to Overthrow the Government." In contrast, Bell's Constitutional Union Party "recognized no other political principles other than the Constitution, the Union of the States, and the Enforcement of Laws."

These 112 pages contain a wealth of material supporting slavery but attacking disunion. Other newspapers and political speeches were quoted at length and proved in-depth looks at the pros and cons of secession from southern viewpoints.
