Through Super Bowl XLII, no. In the 49ers' 5 Super Bowls, they have thrown 163 passes and completed 110 for a completion percentage of 67.5 with 0 passes intercepted. Just found out that the Niners have thrown "0" Super Bowl interceptions. They are the only team with more than two games and no picks. Steve Young nor Joe Montana have thrown any.
As of Super Bowl XLII, that would be Joe Montana of the San Francisco 49ers who threw 36 passes in Super Bowl XXIII against the Cincinnati Bengals without an interception. Additionally, Montana never threw an interception in the four Super Bowls he played in. He threw 122 total passes in the four Super Bowl games without throwing an intereption. Drew Brees broke Joe Montana's record in Super Bowl 44 as he threw 39 passes without an interception.
