Coralie May O'Connor (May 1, 1934 – December 31, 2019) was an American competition swimmer who represented the United States at the 1952 Summer Olympics in Helsinki. O'Connor competed in the preliminary heats of the women's 100-meter backstroke and posted a time of 1:19.7.
Three years later at the 1955 Pan American Games in Mexico City, O'Connor won a gold medal as a member of the first-place U.S. team in the women's 4ÃÂ100-meter medley relay. Her gold medal teammates included Mary Sears, Betty Mullen and Wanda Werner. Individually, she also received a silver medal for finishing second in the women's 100-meter backstroke.
Beginning in the 1960s, O'Connor was for many years the coach of the Worcester Swim Club, a private competitive club that produced numerous prep and college swimmers.
