The 1989 San Francisco Giants season was the Giants' 107th season in Major League Baseball, their 32nd season in San Francisco since their move from New York following the 1957 season, and their 30th at Candlestick Park. The Giants finished in first place in the National League West with a record of 92 wins and 70 losses. It was their second division title in three years. The Giants defeated the Chicago Cubs in five games in the National League Championship Series. However, they were swept by their cross-Bay rivals, the Oakland Athletics, in an earthquake-marred World Series.
