The New-York Tribune was an American newspaper founded in 1841 by editor Horace Greeley. It bore the moniker New-York Daily Tribune from 1842 to 1866 before returning to its original name. From the 1840s through the 1860s it was the dominant newspaper first of the American Whig Party, then of the Republican Party. The paper achieved a circulation of approximately 200,000 in the 1850s, making it the largest daily paper in New York City at the time. The Tribune's editorials were widely read, shared, and copied in other city newspapers, helping to shape national opinion. It was one of the first papers in the North to send reporters, correspondents, and illustrators to cover the campaigns of the American Civil War. It continued as an independent daily newspaper until 1924, when it merged with the New York Herald. The resulting New York Herald Tribune remained in publication until 1966.

The New York Herald Tribune was a newspaper published between 1924 and 1966. It was created in 1924 when Ogden Mills Reid of the New York Tribune acquired the New York Herald. It was regarded as a "writer's newspaper" and competed with The New York Times in the daily morning market. The paper won twelve Pulitzer Prizes during its lifetime.
