Lower Turkeyfoot Township is a township in Somerset County, Pennsylvania, United States. The population was 543 at the 2020 census. It is part of the Johnstown, Pennsylvania, Metropolitan Statistical Area.

Turkeyfoot Township was formed from part of Brothersvalley Township in 1773, when both were still part of a larger Bedford County; Somerset County was not formed from the western portion of Bedford County until 1795. Just as new counties were split off from earlier counties, new townships were split off from earlier townships, and the townships of Upper Turkeyfoot & Lower Turkeyfoot took their current shapes in 1848. White settlers arrived in the Turkeyfoot area by the late 1760s, and a group of about 15-20 Baptist families came to the area from New Jersey around 1774.

The Lower Humbert Bridge was added to the National Register of Historic Places in 1980.
