Lack Township is a township that is located in Juniata County, Pennsylvania, United States. The population was 638 at the time of the 2020 census.[2]


This American township was named by Irish settlers, most likely after Lack, County Fermanagh, although also possibly after Leck, of which there are several places of that name in the Province of Ulster.[3]


According to the United States Census Bureau, the township has a total area of 57.0 square miles (147.7 km2), all land.[4]

The township is located within the Ridge and Valley province of the Appalachian Mountains. Blacklog Mountain forms the northwest border of the township, and Shade Mountain runs parallel to it, 2 miles (3 km) to the southeast. Tuscarora Mountain forms the southeast border of the township. Tuscarora Creek, a northeast-flowing tributary of the Juniata River, runs through the largest valley in the township at the northwestern base of Tuscarora Mountain. Pennsylvania Route 75 traverses the Tuscarora Creek valley, leading northeast to Port Royal and southwest to the Pennsylvania Turnpike in Franklin County.

Pennsylvania Route 35 runs in the same direction through a smaller valley at the southeast foot of Shade Mountain; the highway leads northeast to Mifflin and southwest to Shade Gap.

Lack Township occupies the southwestern end of Juniata County and is bordered by Mifflin County to the northwest, Tuscarora Township to the northeast, Perry and Franklin Counties to the southeast and Huntingdon County to the southwest.

Unincorporated communities in the township include Blacklog and Krause in the valley between Blacklog Mountain and Shade Mountain, Cross Keys and Peru Mills along Pennsylvania Route 35, and Spears Grove, Waterloo, and Perulack along Pennsylvania Route 75 (PA 75). East Waterford, a census-designated place largely in Tuscarora Township, extends west into Lack Township along PA 75.
