Pac-12 Commissioner Larry Scott announced the plans Thursday at Levi's Stadium. The first three conference championships had been held in the stadium of the division champion with the best conference record - Oregon in 2011, Stanford in 2012 and Arizona State last year.
The $1.2 billion stadium, which is located about 45 miles south of San Francisco, is opening this year. It will host the Pac-12 title game this season on Dec. 5.
Scott says the conference is "thrilled to offer student-athletes and their fans the ultimate venue to culminate a successful season."
