The Hawaii Open is a hardcourt men's and women's professional tennis tournament held annually in Honolulu, Hawaii. The tournament features players from the WTA and ATP Tour. The invitational tournament occurs immediately before the ATP Tour and WTA Tour begin the new season in late December.
The Hawaii Open features three rounds of single-elimination matches played over three days in a best two-out-of-three set format. Third sets are played as a tie-break with the first to 10 points declared the winner.
