Club San Cirano is an Argentine rugby union and field hockey club located in the Villa Celina district of La Matanza Partido.

The rugby team currently plays in Primera División A, the second division of the URBA league system.

In 1971, the "Asociación de Ex alumnos del Colegio San Cirano" was created as a social club by former pupils of San Cirano College in Buenos Aires, being named Brian Healy as its first president.

The main sport played at the club has always been rugby union, registering San Cirano with the Unión de Rugby de Buenos Aires in July 1973.

Today the club is mostly competitive at underage levels and has become one of the best rugby academies in Buenos Aires.
