The 1986 Pennsylvania gubernatorial election was held on November 4, 1986. Democrat Bob Casey narrowly defeated Republican Bill Scranton III, in a race that featured two very high-profile candidates.
As of 2024, this is the most recent Pennsylvania gubernatorial race to have a margin within five points for either party. This is the most recent time that the state voted for different parties for Senate and Governor in the same election.
