1989 San Diego Padres season

The 1989 San Diego Padres season was the 21st season in franchise history. The Padres improved on their previous season record of 83–78, and were in contention for the National League West title until the final week of the regular season. However, a 2-1 loss to the Cincinnati Reds on September 27 ended their postseason hopes. The Padres finished in second place at 89–73, three games behind the San Francisco Giants.

This was the Padres' last full season under the ownership of Joan Kroc, who had inherited the franchise following the death of her husband Ray in 1984. Kroc sold the team to a consortium led by Tom Werner the following year.
