Gwynedd was founded in 1698 by Welsh Quakers. The township was then split into Lower Gwynedd and Upper Gwynedd in 1891. The name Gwynedd means "Fair Land" in Welsh.

The township is so named because it was originally settled largely by migrants from Gwynedd and other parts of North Wales in the 17th and 18th centuries. For several generations, the main language used in the township was Welsh.

The Keefe-Mumbower Mill, Knipe-Johnson Farm, Knipe-Moore-Rupp Farm, and Isaac Kulp Farm are listed on the National Register of Historic Places.
