The men's ice hockey tournament at the 1998 Winter Olympics in Nagano, Japan, was the 19th Olympic Championship. The Czech Republic, which emerged from the dissolution of Czechoslovakia in 1993, won its first winter gold medal, becoming only the seventh nation to win Olympic ice hockey gold. The tournament, held from February 7 to February 22, was played at the Big Hat and Aqua Wing arenas.

Ice hockey tournaments have been staged at the Olympic Games since 1920. The men's tournament was introduced at the 1920 Summer Olympics and was transferred permanently to the Winter Olympic Games program in 1924, in France. The women's tournament was first held at the 1998 Winter Olympics.
