Carl Celian Icahn (; born February 16, 1936) is an American financier. He is the founder and controlling shareholder of Icahn Enterprises, a public company and diversified conglomerate holding company based in New York City. Icahn takes large stakes in companies that he believes will appreciate via changes to corporate policy and he then pressures management to make changes that he believes will benefit shareholders. He was one of the first activist shareholders and is credited with making that investment strategy mainstream for hedge funds.In the 1980s, Icahn developed a reputation as a "corporate raider" after profiting from the hostile takeover and asset stripping of Trans World Airlines.Icahn is on the Forbes 400 and has a net worth of approximately $17 billion to $22 billion.Since 2011, Icahn no longer manages money for outside clients, although investors can invest in Icahn Enterprises.

In business, a corporate raid is the process of buying a large stake in a corporation and then using shareholder voting rights to require the company to undertake novel measures designed to increase the share value, generally in opposition to the desires and practices of the corporation's current management. The measures might include replacing top executives, downsizing operations, or liquidating the company. Corporate raids were particularly common in the 1970s, 1980s, and 1990s in the United States. By the end of the 1980s, management of many large publicly traded corporations had adopted legal countermeasures designed to thwart potential hostile takeovers and corporate raids, including poison pills, golden parachutes, and increases in debt levels on the company's balance sheet. In later years, some corporate raiding practices have been used by "activist shareholders", who purchase equity stakes in a corporation to influence its board of directors and put public pressure on its management.
