The 1998 FIL World Lacrosse Championship was the eighth edition of the premier international men's lacrosse tournament. The event took place in Baltimore, Maryland under the auspices of the International Lacrosse Federation. This was the second time that the tournament was held in Baltimore, following the 1982 tournament. Eleven teams competed in the event in two divisions.
The United States successfully defended their title for the fifth consecutive time, defeating Canada 15–14 in double overtime in the final. The championship game – in which Canada overcame a ten-goal deficit to force overtime – is widely considered to be the most exciting lacrosse game in history. Australia beat the Iroquois team 17–5 for third place.
Pool Play
For the pool play phase of the tournament, the teams were divided into two divisions – five in the top Blue Division and six in the Red Division. Only Blue Division participants were able to compete for the championship.
