The 2018 Hong Kong Sevens will be the 43rd edition of the Hong Kong Sevens tournament, and the seventh tournament of the 2017–18 World Rugby Sevens Series.
As in the last tournament, there will be a main draw with the fifteen World Series core teams and one invited team. The teams are drawn into four pools of four teams each. Each team plays all the others in their pool once. 3, 2 or 1 points for a win, draw or loss. The top two teams from each pool advance to the Cup brackets. The bottom two teams go into the Challenge trophy brackets.
There will also be a qualifying tournament featuring twelve teams divided into three pools of four teams each. Each team plays all the others in their pool once. The top eight teams (the top two from each group, plus the two best third-place finishers) qualify to the quarterfinals of the knockout round. The winner of the knockout round will be given core status in the 2018-19 World Series.
