Ivy Ledbetter Lee (July 16, 1877 – November 9, 1934) was an American publicity expert and a founder of modern public relations. Lee is best known for his public relations work with the Rockefeller Family.

His first major client was the Pennsylvania Railroad, followed by numerous major railroads such as the New York Central, the Baltimore and Ohio, and the Harriman lines such as the Union Pacific. He established the Association of Railroad Executives, which included providing public relations services to the industry. Lee advised major industrial corporations, including steel, automobile, tobacco, meat packing, and rubber, as well as public utilities, banks, and even foreign governments

Lee pioneered the use of internal magazines to maintain employee morale, as well as management newsletters, stockholder reports, and news releases to the media. He did a great deal of pro bono work, which he knew was important to his own public image, and during World War I, he became the publicity director for the American Red Cross.
