The O'Connell Superdance is an annual 12 hour dance a thon held at the school which raises money for the Cystic Fibrosis Foundation. The Superdance is organized and run by students. It was started under the administration of principal Msgr. James McMurtrie. O'Connell students began holding the Superdance in 1976 because students wanted to speed the discovery of a cure for cystic fibrosis (CF), a fatal disease of the lungs which had claimed the life of sophomore Brenda O'Donnell on April 14, 1975. Her sister, Maura, was a senior in 1976 and also suffered from cystic fibrosis. Their brother, Sean, died of cystic fibrosis that same year. Maura O'Donnell graduated and went on to nursing school at Marymount University, continuing to support the Superdance in hopes that a cure would be found. Her last Superdance was in 1978 when she came out of the hospital just for the event. In a speech delivered to the O'Connell community, she stated:
"All of you I know have dreams – dreams of college, of success, of love and happiness – dreams of the future. We with cystic fibrosis have dreams too. Your wonderful all out efforts and work for this dance a thon may help make some of our dreams come true." Two months later, she died of this disease. As of 2018, O'Connell students have raised over $4,300,000 for the Cystic Fibrosis Foundation, an organization dedicated to finding a cure for the disease.

At the end of the week, all the cans are displayed on the football field (weather permitting) or inside the auditorium. The student body gathers to celebrate their successful event and pray a special Living Rosary, praying for those who will ultimately benefit from their soup collection.
