William Floyd Weld is an American attorney, businessman, author, and politician who served as the 68th Governor of Massachusetts from 1991 to 1997. A Harvard and Oxford graduate, Weld began his career as legal counsel to the United States House Committee on the Judiciary before becoming the United States Attorney for the District of Massachusetts and later, the United States Assistant Attorney General for the Criminal Division. He worked on a series of high-profile public corruption cases and later resigned in protest of an ethics scandal and associated investigations into Attorney General Edwin Meese.

The 1990 Massachusetts gubernatorial election was held on November 6, 1990. Incumbent Democratic Governor Michael Dukakis, his party's nominee for president in 1988, opted to not seek a fourth term. Republican Bill Weld won the open seat, beating Democrat John Silber to become the first Republican Governor of Massachusetts elected since 1970. This election was the first open-seat gubernatorial election in Massachusetts since 1960.
