The lowest seeded team to make it all the way to the Final Four in the NCAA Basketball tournament was an 11 seed and it happened four times:
11 seeded LSU in 1986
11 seeded George Mason in 2006
11 seeded VCU in 2011
11 seeded Wichita State in 2013
George Mason was the 11th seed in 2006 and made it all the way to the Final Four. I don't know if that's the lowest seeded team to make it to the Elite Eight or Final Four though.http://a.espncdn.com/ncaatourney/brackets/2006Bracket.pdf
