Satan's Kingdom is an unincorporated village in the town of Northfield, Franklin County, Massachusetts, United States.

Satan's Kingdom is 1.5 miles (2.4 km) northwest of the Northfield CDP and is near the Vermont border.

[2][3] Stories say that it was named Satan's Kingdom after a resident of Northfield walked out of a church where a sermon about the fires of hell had just been given and saw a forest fire across the Connecticut River, and observed that Satan's Kingdom was burning.

[4][5] It has also been suggested that the name originated from the village's reputation for dangerous wildlife, such as venomous snakes.
