So proud to wear the Crimson and the Gold!

Chaminade athletes are collectively known as the Flyers. The etymology of the name is two-fold; the Flyers pay tribute to Long Island's significant aviation history, including serving as the landing sites of the first non-stop transcontinental and solo transatlantic crossings. Students may participate on a number of interscholastic teams during three annual seasons.

Chaminade is a founding member of the Nassau-Suffolk Catholic High Schools Athletic Association (CHSAA), a charter member of the Catholic High School Football League, a member of the Catholic High School Athletic Association of Greater New York, and a member of the New York State CHSAA.
