Southern California will make a second straight visit to the Holiday Bowl, where it will play No. 23 Wisconsin on Dec. 30 at Qualcomm Stadium.
USC (8-5) won the Pac-12 South Division before losing to Stanford 41-24 in the conference championship game Saturday night.
The Trojans beat Nebraska 45-42 in last year's Holiday Bowl.
Wisconsin (9-3) was third in the Big Ten West Division. The Badgers are making their 14th consecutive bowl appearance, the longest active streak in the Big Ten and tied for the sixth-longest streak in the country.
The Badgers have the top-ranked scoring defense in the country, allowing just 13.1 points per game.
The Trojans have won five of their last eight games since Clay Helton was named interim head coach on Oct. 12. The school removed the interim tag last week.
