The election of the Governor of the Commonwealth of Pennsylvania occurs when voters in the U.S. Commonwealth of Pennsylvania select the Governor and Lieutenant Governor for the ensuing four years beginning at noon on the third Tuesday of January following the election. Pennsylvania gubernatorial elections were held beginning with the first election in 1790 until 1878. Gubernatorial elections have been held since the election of 1882. Gubernatorial general elections are held on Election Day, coinciding with various other federal, statewide, and local races. Per Article II of the 1790 Pennsylvania Constitution, gubernatorial elections were held triennially on the second Tuesday of October, with the three-year term commencing on the third Tuesday of December immediately following the election. Incumbents were permitted to serve for a maximum of nine years out of any period of twelve years. Ties were to be resolved, pursuant to the same document, by a joint vote of the Pennsylvania General Assembly, consisting ofthe House of Representatives and the Senate. The 1874 Pennsylvania Constitution mandated the date of gubernatorial elections to be likewise that of the general election on Election Day in November and extended the term to four years, beginning on the third Tuesday of January following the election. In the original text of the 1874 Constitution, an incumbent governor was prohibited from running for a second successive term, but this was amended in 1967 to permit an incumbent to do so. The next gubernatorial election in Pennsylvania is scheduled to be held on November 8, 2022.
