The 1958 Little League World Series took place on August 19 through 22 in Williamsport, Pennsylvania. Industrial Little League of Monterrey, Nuevo León, Mexico, won its second consecutive Little League World Series (LLWS) by defeating the Jaycee Little League of Kankakee, Illinois, in the 12th championship game. The Monterrey, Nuevo León, Mexico team was the first team to win in consecutive years, a feat only matched by Seoul, South Korea (1984/1985) and Long Beach, California (1992/1993).

This was the last LLWS to be played at Original Field in Williamsport. This was the first LLWS to include teams from more than four qualifying regions, and also the first to give automatic berths to teams from Canada, represented by the Valleyfield Little League of Valleyfield, Quebec, and to Latin America, represented by Monterrey.
