Greenmail or greenmailing is the action of purchasing enough shares in a firm to challenge a firm's leadership with the threat of a hostile takeover to force the target company to buy the purchased shares back at a premium in order to prevent the potential takeover. The term is a financial neologism, coined in the 1980s, from blackmail and greenback as commentators and journalists saw the practice of corporate raiders as attempts by well-financed individuals, or their operating companies, to blackmail a company into handing over money by using the threat of a takeover. The greenmail strategy has evolved since its first practices with ways to counter greenmail, other variations of greenmail, as well as ways to reinforce a greenmail tactic. In the area of mergers and acquisitions, the greenmail payment is made in an attempt to stop the hostile takeover.

In other circumstances, the greenmailer seeks out assets the target company has built up as equity, such as real estate, and attempts to have the target company dispose of those assets and lease them back via a recurring lease payment, while returning the sold-off real estate to shareholders as a special dividend. One example of this practice was the attempted takeover by William Ackman's Pershing Square Capital Management of American retailer Target, which had a large inventory of mature or nearly mature real estate properties in its corporate portfolio. Ackman attempted to have these assets spun off as an IPO, along with a partial sale of Target's credit card unit and the execution of share buybacks, which reduce the number of shares outstanding by using corporate equity and earnings to repurchase existing shareholders' positions. Once having secured a large share of a target company, instead of completing the hostile takeover, the greenmailer offers to end the threat to the victim company by selling his share back to it, but at a substantial premium to the fair market stock price. From the viewpoint of the target, the ransom payment may be referred to as a goodbye kiss. The origin of the term goodbye kiss as a business metaphor is unclear. In reference to a President, Chairman, or CEO in charge of a target company being taken over, there
