The Jamnabai Narsee Alumni Association (JNAA), established in January 1984, is one of Mumbai's largest ex - student bodies comprising over ten thousand members over the last 40 years. The JNAA aims to maintain a strong connection between the students of Jamnabai Narsee School and their alma mater.

Throughout the year, the managing committee and working committee of the Association conduct various activities and events directed not only towards the networking of its members but also towards the betterment of the society.

Events organised by the JNAA include periodical reunions, inter - batch sports tournaments, the JNAA Grand Debate between teachers, students and ex - students, social gatherings, career fairs, festive celebrations, treks, camps, marathons and donation drives.

The JNAA also organises the state's largest inter-school cultural festival, 'Cascade' on a yearly basis with great success. The event has evolved by leaps and bounds over the last two decades consistently witnessing a yearly participation of over fifty schools.

Thus the association is dedicated to the cause of strengthening the link between each and every student and teacher of Jamnabai Narsee School.
