Native American tribes in Pennsylvania

The Mohawk, also known by their own name, Kanien'kehá:ka (lit. 'People of the flint'), are an Indigenous people of North America and the easternmost nation of the Haudenosaunee, or Iroquois Confederacy (also known as the Five Nations or later the Six Nations).

The Erie people were an Indigenous people of the Northeastern Woodlands historically living on the south shore of Lake Erie. An Iroquoian-speaking tribe, they lived in what is now western New York, northwestern Pennsylvania, and northern Ohio before 1658. Their nation was almost exterminated in the mid-17th century by five years of prolonged warfare with the powerful neighboring Iroquois for helping the Huron in the Beaver Wars for control of the fur trade. Captured survivors were adopted or enslaved by the Iroquois.

The Lenape, also called the Lenni Lenape and Delaware people, are an Indigenous people of the Northeastern Woodlands, who live in the United States and Canada.

The Nanticoke people are a Native American Algonquian-speaking people, whose traditional homelands are in Chesapeake Bay area, including Delaware. Today they continue to live in the Northeastern United States, especially Delaware, and in Oklahoma. They also live in Ontario, Canada, where some ancestors resettled with Iroquois nations after the Revolutionary War.

The Munsee (Delaware: Monsiyok) are a subtribe and one of the three divisions of the Lenape. Historically, they lived along the upper portion of the Delaware River, the Minisink, and the adjacent country in New York, New Jersey, and Pennsylvania. They were prominent in the early history of New York and New Jersey, being among the first Indigenous peoples of that region to encounter European colonizers.

The Monongahela culture were an Iroquoian Native American cultural manifestation of Late Woodland peoples from AD 1050 to 1635 in present-day Western Pennsylvania, western Maryland, eastern Ohio, and West Virginia. The culture was named by Mary Butler in 1939 for the Monongahela River, whose valley contains the majority of this culture's sites.

The Susquehannock, also known as the Conestoga, Minquas, and Andaste, were an Iroquoian people who lived in the lower Susquehanna River watershed in what is now Pennsylvania. Their name means “people of the muddy river.”

The Shawnee (shaw-NEE) are a Native American people of the Northeastern Woodlands. Their language, Shawnee, is an Algonquian language.

The Seneca (SEN-ik-ə; Seneca: O-non-dowa-gah/Onöndowa'ga:', 'Great Hill People') are a group of Indigenous Iroquoian-speaking people who historically lived south of Lake Ontario, one of the five Great Lakes in North America. Their nation was the farthest to the west within the Six Nations or Iroquois League (Haudenosaunee) in New York before the American Revolution. For this reason, they are called “The Keepers of the Western Door.”

The Treaty of Shackamaxon, also called the Great Treaty and Penn's Treaty, was a treaty between William Penn and Tamanend of the Lenape signed in 1682. The treaty created peace between the Quakers and Lenape, with Tamanend saying the two would "live in peace as long as the waters [ran] in the rivers and creeks and as long as the stars and moon [endured]."
