Yes.
In fact,
in the 2013 NCAA men's Basketball tournament, the #12 seed beat the #5 seed in three of the four regionals:
California over UNLV 64-61 in the East; Oregon over Oklahoma State 68-55 in the Midwest; and Mississippi over Wisconsin 57-46 in the West.
Through 2013, there have been
11 games in the NCAA men's basketball tournament that were played between #12 and #13 seeds. The #12 seeds have won eight of these games, but the sole 2013 occasion was won by #13 LaSalle
over #12 Mississippi (Ole Miss).
Since 1985 when the NCAA Turnament expanded to 64 teams the No. 12 seed has beaten the number 5 seed 35 times. Or about 1 out of three.
