The 2013 Little League World Series was held in South Williamsport, Pennsylvania, from August 15 until August 25. Eight teams from the United States and eight from throughout the world competed in the 67th edition of the Little League World Series (LLWS). The Musashi-Fuchū Little League of Tokyo, Japan, defeated the Eastlake Little League of Chula Vista, California, 6–4 in the championship game. For Japan, this was their ninth LLWS championship overall, second consecutive, and the third in four years. This was the last LLWS to feature players born in the 20th century.

It was announced on August 29, 2012 that three of the eight international regions had been realigned. The results of the realignment included Australia having its own region, meaning that the national champion of that country would be given a berth into the Little League World Series. Also, teams from Middle Eastern countries (except Israel and Turkey) would compete to qualify with teams in the Asia-Pacific Region to form the Asia-Pacific and Middle East region. Teams from Africa would compete to qualify with teams from Europe to form the Europe and Africa region.

The drawing to determine the opening round pairings took place on June 13, 2013.

Teams that lost their first two games played a crossover game against a team from the other side of the bracket that also lost its first two games. These games were labeled Game A and Game B. This provided teams who were already eliminated the opportunity to play a third game.

The consolation game is played between the loser of the United States championship and the loser of the International championship.

Grant Holman of the Eastlake Little League (Chula Vista, California) tossed a no-hitter in the fourth game of the tournament against Grosse Pointe, Michigan.

The Musashi Fuchū LL reached the LLWS by winning all eight of their Tokyo and national tournament games. In total, they went undefeated with a 13–0 record.
