David Alan Mamet (born November 30, 1947) is an American author, essayist, playwright, screenwriter and film director. His works are known for their clever, terse, sometimes vulgar dialogue, arcane stylized phrasing, and for his exploration of masculinity.

As a playwright, he received Tony nominations for Glengarry Glen Ross (1984) and Speed-the-Plow (1988). As a screenwriter, he received Oscar nominations for The Verdict (1982) and Wag the Dog (1997).

Speed-the-Plow's Broadway run is the most recent triumph of the Pulitzer Prize-winning author's astonishingly productive career. "By turns hilarious and chilling....the culmination of this playwright's work to date....Riveting theater."-Frank Rich, New York Times; "A brilliant black comedy, a dazzling dissection of Hollywood cupidity and another tone poem by our foremost master of the language of moral epilepsy... On its deepest level it belongs with the darker disclosures of movie-biz pathology like Nathanael West's The Day of the Locust and F. Scott Fitzgerald's The Last Tycoon. In a sense Speed-the-Plow distills all of these to a stark quintessence: there's hardly a line in it that isn't somehow insanely funny or scarily insane... [It is a] scathingly comic play."-Jack Kroll, Newsweek
