The 1999 San Francisco 49ers season was the team's 50th year with the National Football League. This would also be Steve Young's last season as he was forced to retire due to concussions.
San Francisco started the season with a 3–1 record, but Young suffered his season- and career-ending concussion against the Arizona Cardinals in Week 3. After defeating the Cardinals and the Tennessee Titans without Young, the 49ers went on to lose ten of the remaining eleven games of the season. It was the first time the team had missed the postseason since 1991, their second time missing the postseason in 17 seasons, and their first losing season in a non-strike year (as well as their first season without at least 10 wins) since 1980.
Statistics site Football Outsiders calculates that the 1999 49ers had the second-worst pass defense they had ever tracked.
