The Salem witch trials were a series of hearings and prosecutions of people accused of witchcraft in colonial Massachusetts between February 1692 and May 1693. More than 200 people were accused. Thirty people were found guilty, 19 of whom were executed by hanging (14 women and five men). One other man, Giles Corey, was pressed to death after refusing to enter a plea, and at least five people died in jail.

Arrests were made in numerous towns beyond Salem and Salem Village (known today as Danvers), notably Andover and Topsfield. The grand juries and trials for this capital crime were conducted by a Court of Oyer and Terminer in 1692 and by a Superior Court of Judicature in 1693, both held in Salem Town, where the hangings also took place. It was the deadliest witch hunt in the history of colonial North America. Only fourteen other women and two men had been executed in Massachusetts and Connecticut during the 17th century.

The episode is one of Colonial America's most notorious cases of mass hysteria. It was not unique, but a colonial manifestation of the much broader phenomenon of witch trials in the early modern period, which took the lives of tens-of-thousands in Europe. In America, Salem's events have been used in political rhetoric and popular literature as a vivid cautionary tale about the dangers of isolation, religious extremism, false accusations, and lapses in due process. Many historians consider the lasting effects of the trials to have been highly influential in the history of the United States.
