1986 Amateur World Series

The 1986 Amateur World Series was the 29th Amateur World Series (AWS), an international Men's amateur baseball tournament. The tournament was sanctioned by the International Baseball Federation (IBAF). The tournament took place, for the first time, in the Netherlands, from July 19 to August 2, and was won by Cuba – its 18th AWS victory.

There were 12 participating countries.

This was the last time the IBAF titled it as the AWS; the next ten competitions were held under the name Baseball World Cup, then was replaced in 2015 by the quadrennial WBSC Premier12.
