The 1957 Little League World Series took place during August 21 through 23 in Williamsport, Pennsylvania. Industrial Little League of Monterrey, Nuevo León, Mexico, defeated Northern La Mesa Little League of La Mesa, California, in the championship game of the 11th Little League World Series (LLWS). Ángel Macías threw the first and, to date, only perfect game in an LLWS championship.
This was the first LLWS to invite teams from qualifying regions: North, South, East, and West. Monterrey, representing the South region, became the first team from outside the United States or Canada to participate in a LLWS, and the first non-U.S. team to win a championship.
