1988 San Francisco 49ers season

The 1988 season was the San Francisco 49ers' 39th in the National Football League (NFL), their 43rd overall, and their tenth and final season under head coach Bill Walsh. The 49ers won their third Super Bowl victory after a challenging regular season, with the team slipping to a 6–5 record in week 11. In danger of missing the playoffs for the first time since 1982, they defeated the Washington Redskins on a Monday night and won four of their last five regular season games, finishing the season 10-6 as NFC West champions. In the divisional round of the playoffs, they thrashed the Minnesota Vikings 34–9, gaining revenge over the side that had upset the #1-seeded 49ers at the same point in the previous season. They then defeated the Chicago Bears 28–3 in the NFC Championship game, braving a wind-chill factor of 26 degrees below zero.

Super Bowl XXIII marked the 49ers first Super Bowl appearance since they defeated the Miami Dolphins in Super Bowl XIX. They had made the playoffs in the three intervening seasons, but were eliminated each time in the first round, primarily because of the poor performances by their offensive stars in those games; quarterback Joe Montana, receiver Jerry Rice and running back Roger Craig all failed to produce a single touchdown.

The 49ers alternated quarterbacks, as Montana and Steve Young both started at various points of the season. The broadcast booth of the 49ers radio network also saw change, as Joe Starkey substituted for longtime 49ers play by play announcer Lon Simmons during several games, mostly in October when Simmons called the Oakland Athletics 1988 American League Championship Series and 1988 World Series games for the Oakland A's flagship station, KSFO. The 1988 season was the last for Simmons as 49ers broadcaster. Across the regular season and postseason, the 49ers won just 13 games, then a record-low for Super Bowl champions. The number was matched in 2011 by the New York Giants, who also finished with a worse record: 13–7 (.650 win percentage), compared to the 49ers’ 13–6 (.684).

NFL Films produced a documentary about the team's season entitled State of the Art; it was narrated by Jeff Kaye. On March 8, 2007, NFL Network aired America's Game: The Super Bowl Champions, the 1988 San Francisco 49ers, with team commentary from Bill Walsh, Harris Barton and Roger Craig, and narrated by Ed Harris.
