The coat of arms of Pennsylvania is an official emblem of the Commonwealth of Pennsylvania, alongside the seal and state flag, and was adopted in 1778.

The state seal of Pennsylvania was authorized by the Pennsylvania General Assembly in 1791, and is "a symbol of authenticity which verifies that proclamations, commissions and other papers of state are legal and official."

Unlike most state seals, it has an obverse and a reverse. The Secretary of the Commonwealth is the keeper of the seal, and has the duty of authenticating government documents, and proclaiming new law as enacted through its use.
