when were the vikings in the super bowl

The Minnesota Vikings have been to the Super Bowl four times, all in the 1970s, and they lost each appearance.
Here’s the quick breakdown:
- Super Bowl IV – January 11, 1970 vs. Kansas City Chiefs (Vikings lost 23–7).
- Super Bowl VIII – January 13, 1974 vs. Miami Dolphins (Vikings lost 24–7).
- Super Bowl IX – January 12, 1975 vs. Pittsburgh Steelers (Vikings lost 16–6).
- Super Bowl XI – January 9, 1977 vs. Oakland Raiders (Vikings lost 32–14 or 42–14 depending on source reporting, but all agree it was a loss).
They have never won a Super Bowl, and their last appearance was that Super Bowl XI matchup in January 1977.
