Snowboarding at the 2018 Winter Olympics – Men's big air

The top 40 athletes in the Olympic quota allocation list qualified (for both big air and slopestyle, the rankings were combined). This meant only a maximum of 40 could qualify across both events. A maximum of four athletes per National Olympic Committee (NOC) was allowed. All athletes qualifying must also have placed in the top 30 of a FIS World Cup event (in either big air or slopestyle) or the FIS Freestyle Ski and Snowboarding World Championships 2017 during the qualification period (1 July 2016 to 21 January 2018) and also have a minimum of 50 FIS points to compete. If the host country, South Korea, did not qualify, their chosen athlete would displace the last qualified athlete, granted all qualification criterion was met.^[5]
