List of colonial governors of Pennsylvania

Three generations of Penns acted as proprietors of the Province of Pennsylvania and the Lower Counties (Delaware) from the founding of the colony until the American Revolution removed them from power. William Penn was granted the new proprietary colony in 1681 by Charles II of England in payment for debts owed to Penn's father. After Penn became ill in 1712, his second wife Hannah Callowhill Penn served as acting proprietor.

After William's death in 1718, interest in the proprietorship passed to his three sons by Hannah: John Penn "the American", Thomas Penn, and Richard Penn, Sr., with John inheriting the largest share and becoming the chief proprietor. When John died without children, his brother Thomas inherited his share and became chief proprietor.

When Richard Penn, Sr. died, his share passed to his son Governor John Penn. When Thomas Penn died, his share (and the chief proprietorship) passed to his son John Penn "of Stoke".

The government of Colonial Pennsylvania (and the Lower Counties) was conducted by a set of administrators in the name of the proprietors.

During the British occupation of Philadelphia from 26 September 1777 until June 1778, Joseph Galloway was "in charge of policing the city, and of imports and exports".
