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 between the 1970s and the 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.
