The lieutenant governor is a constitutional officer of the Commonwealth of Pennsylvania. The lieutenant governor is elected for a four-year term in the same year as the governor. Each party picks a candidate for lieutenant governor independently of the gubernatorial primary. The winners of the party primaries are then teamed together as a single ticket for the fall general election.  Michael J. Stack III is the incumbent lieutenant governor. The lieutenant governor presides in the Senate and is first in the line of succession to the governor; in the event the governor dies, resigns, or otherwise leaves office, the lieutenant governor becomes governor.
The office of lieutenant governor was created by the Constitution of 1873. As with the governor's position, the Constitution of 1968 made the lieutenant governor eligible to succeed himself or herself for one additional four-year term.  The position's only official duties are serving as president of the state senate and chairing the Board of Pardons and the Pennsylvania Emergency Management Council. Lieutenant governors often work on additional projects and have a full schedule of community and speaking events. Pennsylvania is the only state that provides a residence (the "State House" at Fort Indiantown Gap) for its lieutenant governor.  Constructed in 1940 and previously the governor's "summer residence", it became available for Pennsylvania's lieutenant governor in 1968 when the current governor's residence was completed in Harrisburg. 
As of January 2017 [update], six former U.S. Lieutenant Governors of Pennsylvania were alive, the oldest being Robert C. Jubelirer (served 2001–2003, born 1937). The most recent death of a former U.S. lieutenant governor of Pennsylvania was that of Ernest P. Kline (served 1971–1979, born 1929), on May 13, 2009. The most recently serving lieutenant governor to die was Catherine Baker Knoll (2003-2008), who died in office on November 12, 2008.

From 1777 to 1790 the executive branch of Pennsylvania's state government was headed by a Supreme Executive Council consisting of a representative of each county and of the City of Philadelphia. The Vice President of the Council—also known as the Vice-President of Pennsylvania—held a position analogous to the modern office of Lieutenant Governor. Presidents and Vice-Presidents were elected to one-year terms and could serve up to three years—the full length of their regular term as Counsellor. Ten men served as Vice-President during the time of the Council's existence.
