The NCAA Division I softball tournament is held annually in May/June and features 64 college softball teams in the United States, culminating in the Women's College World Series (WCWS), which is played in Oklahoma City.

32 teams gain automatic entry into the tournament while the other 32 are selected by the Division I Softball committee.

[1] The first round of the tournament, called "regionals", consists of 16 locations that include four teams competing in a double elimination bracket.

The final eight teams meet at USA Softball Hall of Fame Stadium in Oklahoma City in the Women's College World Series.

The first part resembles the regional round, as teams are broken in two groups of four to play in a double-elimination bracket.
