Miss USA 1964

Miss USA 1964 was the 13th Miss USA pageant, held in Miami Beach, Florida on July 29, 1964. This was the last Miss USA pageant to be held as an inclusive part of the Miss Universe event.

The pageant was won by Bobbi Johnson of the District of Columbia, who was crowned by outgoing titleholder Marite Ozers of Illinois. Two days after her victory, Johnson went on to place as a top 15 semi-finalist at Miss Universe 1964.

Johnson was the first woman from Washington D.C. to win the title.

This was the latest Miss USA pageant ever held on this date until the 2020 competition. The rescheduling of the pageant as an independent event from Miss Universe in 1965 meant Johnson reigned for only 10 months and 6 days; apart from first runners-up who inherited the crown when Miss USA won Miss Universe, only 1986 titleholder Christy Fichtner had a shorter reign (8 months and 28 days).
