The 2016 Rio Olympics are officially underway already, though our flag-waving ways really get started on Friday night with the opening ceremony. As each country parades its delegation around for the world to see, college sports fans everywhere will recognize the faces of some of their favorite current and former athletes.

No fans have more reason to be excited to see their schools represented on the world's biggest stage than the ones out west in the Pac-12, which dwarfs all other conferences with 273 current or former athletes in the 2016 Rio Olympics. The foursome of California,USC, Stanford and UCLA hold the top spots on the list of most-represented schools. In fact, those four schools alone have more Olympians combined than any other individual conference other than the SEC.

Check out the top 25 most-represented schools below, followed by a ranking of the Power Five conferences with the top schools from each league included.
