The Yazoo land scandal, Yazoo fraud, Yazoo land fraud, or Yazoo land controversy was a massive real-estate fraud perpetrated, in the mid-1790s, by Georgia governor George Mathews and the Georgia General Assembly. Georgia politicians sold large tracts of territory in the Yazoo lands, in what are now portions of the present-day states of Alabama and Mississippi, to political insiders at very low prices in 1794. Although the law enabling the sales was overturned by reformers the following year, its ability to do so was challenged in the courts, eventually reaching the US Supreme Court. In the landmark decision in Fletcher v. Peck (1810), the Court ruled that the contracts were binding and the state could not retroactively invalidate the earlier land sales. It was one of the first times the Supreme Court had overturned a state law, and it justified many claims for those lands. Some of the land sold by the state in 1794 had been shortly thereafter resold to innocent third parties, greatly complicating the litigation. In 1802, because of the ongoing controversy, Georgia ceded all of its claims to lands west of its modern border to the U.S. government. In exchange the government paid cash and assumed the legal liabilities. Claims involving the land purchases were not fully resolved until legislation was passed in 1814 establishing a claims-resolution fund.

George Mathews was an American soldier and politician from the U.S. States of Virginia and Georgia. He was a brevet brigadier general in the Continental Army, the 20th and 24th Governor of Georgia, a U.S. Representative from Georgia, and the leading participant in the Patriot War of East Florida.
