2019 Alpine Skiing World Cup – Men's giant slalom

The men's giant slalom in the 2019 FIS Alpine Skiing World Cup involved nine events, including a parallel giant slalom. After this season, all parallel races were moved into a separate discipline. Marcel Hirscher of Austria won three of the first four races this season and easily won the discipline for the fifth straight season, his sixth total win in this discipline, on his way to his eighth straight overall World Cup championship.

The season was interrupted by the 2019 World Ski Championships, which were held from 4–17 February in Åre, Sweden. The men's giant slalom was held on 15 February.
