The 2010 World Junior Baseball Championship was an international baseball competition being held at the Port Arthur Stadium and Central Ball Park in Thunder Bay, Ontario, Canada from July 23 to August 1, 2010.

Teams

Just before the tournament started on July 23, the organization had to announce that the team from Venezuela would not attend the tournament. However, on the second day of the tournament it was announced that Venezuela has joined the other 11 nations. The original schedule remained in place, and Venezuela forfeited its first scheduled game on July 23, giving a 9–0 win to Australia. That game will not be made up. The following 12 teams qualified for the tournament.
