There is at least one team in each division that has not won the Super Bowl yet.
Update: This post has been updated to reflect the Eagles winning Super Bowl LII, bringing the number of franchises without a Super Bowl title down to 12.
There are 12 NFL franchises that have not won a Super Bowl.
The Bengals, Bills, Browns, Cardinals, Chargers, Falcons, Jaguars, Lions, Panthers, Texans, Titans and Vikings have not won a Super Bowl in their history. The Browns, Jaguars, Lions and Texans have never reached the Super Bowl.
Among the nine teams that have played in a Super Bowl, five have appeared multiple times. The Falcons were the last team in the group to appear in a Super Bowl, playing against the Patriots in Super Bowl LI. Atlanta led 28-3 at one point late in the third quarter but went on to blow the biggest lead in Super Bowl history, losing 34-28 in overtime.
The Jaguars and Vikings both made their conference championships last season, but another team without a Super Bowl ring—the Eagles—ended up winning Super Bowl LII.
