The USBC Queens is an annual ten-pin bowling event for amateur and professional female bowlers, sanctioned by the United States Bowling Congress. The event is one of two women's professional majors and the female equivalent of the USBC Masters, now one of the four majors on the Professional Bowlers Association (PBA) Tour. Nine bowlers have won at least two USBC Queens titles, with only two winning three times: Millie Ignizio (Martorella) (1967, 1970, 1971) and Wendy Macpherson (1988, 2000, 2003). Both bowlers are now in the USBC Hall of Fame.
