Sodom Schoolhouse is a historic octagonal school in West Chillisquaque Township, Northumberland County, Pennsylvania, United States reportedly built about 1812, 1835, or 1836 and used until 1915.

[3][4] It is located in a rural area on Pennsylvania Route 45 near several Scotch-Irish communities: the "small group of houses" formerly known as Sodom, which was about a mile east of the hamlet of Montandon, and about 3 miles east of a small town, Lewisburg.

The inside was painted slate grey, and a wood-burning stove stood in the center.

[7] The hamlets of Montandon and Sodom, however, were not established until the 1830s[5] and 1835 is a more commonly accepted construction date.

[6] One source suggests that octagonal schools are related to a Quaker educational movement that started about 1800 in England as the Industrial Revolution was beginning.
