Which sport made its Olympic debut at the 2016 Rio Games?

Rugby sevens made its Olympic debut at the 2016 Rio Games.

The sport is a shortened, faster version of rugby union, with seven players per team instead of 15 and matches typically lasting 14 minutes. Its compact format made it well suited to an Olympic schedule and helped introduce rugby to audiences unfamiliar with the traditional 15-a-side game.

Rugby sevens was contested in both the men's and women's tournaments in Rio. Fiji won the men's gold medal—the country's first-ever Olympic medal—while Australia won the inaugural women's Olympic tournament. The matches were played at Deodoro Stadium.

Golf can cause confusion because it also appeared in Rio after a long absence, but it was returning to the Olympics rather than making its debut. Golf had previously been played at the 1900 and 1904 Games. Beach volleyball and handball were already Olympic sports before 2016.
