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.

A "Republican paper, a Protestant paper and a paper more representative of the suburbs than the ethnic mix of the city", according to one later reporter, the Tribune generally did not match the comprehensiveness of The New York Times' coverage. Its national, international and business coverage, however, was generally viewed as among the best in the industry, as was its overall style. At one time or another, the paper's writers included Dorothy Thompson, Red Smith, Roger Kahn, Richard Watts Jr., Homer Bigart, Walter Kerr, Walter Lippmann, St. Clair McKelway, Judith Crist, Dick Schaap, Tom Wolfe, John Steinbeck, and Jimmy Breslin. Editorially, the newspaper was the voice for eastern Republicans, later referred to as Rockefeller Republicans, and espoused a pro-business, internationalist viewpoint.

The paper, first owned by the Reid family, struggled financially for most of its life and rarely generated enough profit for growth or capital improvements; the Reids subsidized the Herald Tribune through the paper's early years. However, it enjoyed prosperity during World War II and by the end of the conflict had pulled close to the Times in ad revenue. A series of disastrous business decisions, combined with aggressive competition from the Times and poor leadership from the Reid family, left the Herald Tribune far behind its rival.

In 1958, the Reids sold the Herald Tribune to John Hay Whitney, a multimillionaire Wall Street investor who was serving as ambassador to the United Kingdom at the time. Under his leadership, the Tribune experimented with new layouts and new approaches to reporting the news and made important contributions to the body of New Journalism that developed in the 1960s. The paper steadily revived under Whitney, but a 114-day newspaper strike stopped the Herald Tribune's gains and ushered in four years of strife with labor unions, particularly the local chapter of the International Typographical Union. Faced with mounting losses, Whitney attempted to merge the Herald Tribune with the New York World-Telegram and the New York Journal-American in the spring of 1966; the proposed merger led to another lengthy strike, and on August 15, 1966, Whitney announced the closure of the Herald Tribune. Combined with investments in the World Journal Tribune, Whitney spent $39.5 million (equivalent to $382,573,050 in 2024 dollars) in his attempts to keep the newspaper alive.

After the New York Herald Tribune closed, the Times and The Washington Post, joined by Whitney, entered an agreement to operate the International Herald Tribune, the paper's former Paris publication. By 1967, the paper was owned jointly by Whitney Communications, The Washington Post and The New York Times. The International Herald Tribune, also known as the "IHT", ceased publication in 2013.

The New York Herald was founded on May 6, 1835, by James Gordon Bennett, a Scottish immigrant who came to the United States aged 24. Bennett, a firm Democrat, had established a name in the newspaper business in the 1820s with dispatches sent from Washington, D.C., to the New York Enquirer, most sharply critical of President John Quincy Adams and Secretary of State Henry Clay; one historian called Bennett "the first real Washington reporter". Bennett was also a pioneer in crime reporting; while writing about a murder trial in 1830, the attorney general of Massachusetts attempted to restrict the coverage of the newspapers: Bennett criticized the move as an "old, worm-eaten, Gothic dogma of the Court...to consider the publicity given to every event by the Press, as destructive to the interests of law and justice". The fight over access eventually overshadowed the trial itself.

Bennett founded the New York Globe in 1832 to promote the re-election of Andrew Jackson to the White House, but the paper quickly folded after the election. After a few years of journalistic piecework, he founded the Herald in 1835 as a penny newspaper, similar in some respects to Benjamin Day's Sun but with a strong emphasis on crime and financial coverage; the Herald "carried the most authentic and thorough list of market prices published anywhere; for these alone it commanded attention in financial circles". Bennett, who wrote much of the newspaper himself, "perfected the fresh, pointed prose practiced in the French press at its best". The publisher's coverage of the 1836 murder of Helen Jewett—which, for the first time in the American press, included excerpts from the murder victim's correspondence—made Bennett "the best known, if most notorious…journalist in the country".

Bennett put his profits back into his newspaper, establishing a Washington bureau and recruiting correspondents in Europe to provide the "first systematic foreign coverage" in an American newspaper. By 1839, the Herald's circulation exceeded that of The London Times. When the Mexican–American War broke out in 1846, the Herald assigned a reporter to the conflict—the only newspaper in New York to do so—and used the telegraph, then a new technology, to not only beat competitors with news but provide Washington policymakers with the first reports from the conflict. During the American Civil War, Bennett kept at least 24 correspondents in the field, opened a Southern desk and had reporters comb the hospitals to develop lists of casualties and deliver messages from the wounded to their families.
