Qualifier 3 of the Qualifying Round of the 2013 World Baseball Classic was held at Rod Carew Stadium, Panama City, Panama from November 15 to 19, 2012.
Qualifier 3 was a modified double-elimination tournament. The winners for the first games matched up in the second game, while the losers faced each other in an elimination game. The winners of the elimination game then played the losers of the non-elimination game in another elimination game. The remaining two teams then played each other to determine the winners of the Qualifier 3.
