List of governors of Pennsylvania

The governor of Pennsylvania is the head of government of the Commonwealth of Pennsylvania, as well as commander-in-chief of the state's national guard.

The governor has a duty to enforce state laws and the power to approve or veto bills passed by the Pennsylvania General Assembly, as well as to convene the legislature. The governor may grant pardons except in cases of impeachment, but only when recommended by the Board of Pardons.

There have been seven presidents and 48 governors of Pennsylvania, with two governors (Robert E. Pattison and Gifford Pinchot) serving non-consecutive terms, totaling 55 terms in both offices. The longest term was that of the first governor, Thomas Mifflin, who served three full terms as governor in addition to two years as President of the Continental Congress. The shortest term belonged to John C. Bell Jr., who served only 19 days as acting governor after his predecessor, Edward Martin, resigned.

The current governor is Josh Shapiro, who took office on January 17, 2023.

Pennsylvania was one of the original Thirteen Colonies and was admitted as a state on December 12, 1787. Before it declared its independence, Pennsylvania was a colony of the Kingdom of Great Britain.

The Pennsylvania Constitution of 1776 created the Supreme Executive Council as the state's executive branch, with a president as its head. The president was chosen annually by the council, though with no specific term dates.

The constitution created the position of "vice-president", though no provision was made if the office of the president became vacant, which occurred four times later. Contemporary sources continue to label the chief executive in such times as the vice-president, without any notion of succeeding in the presidency. One acting president, George Bryan, was subsequently recognized later as a full-fledged governor, due to his acting as president for over six months.

The 1790 constitution abolished the council and replaced the president with a governor, and established a three-year term for governor commencing on the third Tuesday of the December following the election, with governors not allowed to serve more than nine out of any twelve years. The 1838 constitution moved the start of the term to the third Tuesday of the January following the election, and allowed governors to only serve six out of any nine years. The 1874 constitution lengthened the term to four years, and prohibited governors from succeeding themselves. The current constitution of 1968 changed this to allow governors to serve two consecutive terms, with no lifetime limit.
