San Bernardino County investigators say the women were arguing and it got physical in a field near the June ceremony at Puesta del Sol Elementary in Victorville.
Several men got involved and the incident turned into a brawl, forcing school officials to place the school on lockdown until deputies sorted things out. No one was hurt.
Court records show misdemeanor charges have been filed against 31-year-old Queiona Burt and 29-year-old Marina Ruth Vargas.
Prosecutors say they face up to six months in jail if convicted for interference with peaceful conduct at a school and 90 days in jail for unlawful acts committed on school grounds.
