INTERACT is an international organization of service and social clubs for young people of secondary school age that fosters leadership and responsible citizenship and promotes international understanding and peace. The name was created by combining the words "international" and "action." INTERACT clubs are sponsored by Rotary clubs as a program of Rotary International. Rotary clubs provide guidance and inspiration, but the INTERACT clubs are self-governing and self-supporting. Clubs take a variety of forms, both single-gender and mixed as well as large and small. The membership base of a club can be drawn from the student body of a single school or from two or more schools from the same community.

Each year, INTERACT clubs complete at least one community service project and at least one project that furthers international understanding and goodwill. INTERACTors develop a worldwide network of friendships through exchanges with local and overseas clubs. Along the way, INTERACTors develop their leadership skills and initiative while meeting new friends  Through their service activities, INTERACTors learn the importance of:

• Developing leadership skills and personal integrity
• Demonstrating helpfulness and respect for others
• Understanding the value of individual responsibility and hard work
• Advancing international understanding and goodwill

The first INTERACT club was initiated in 1962 by the Rotary Club of Melbourne, Florida, USA. Two months later, the first INTERACT club outside the United States was established in Tanjore, India. Today there are more than 6,650 INTERACT clubs in some 103 countries and geographical areas, making INTERACT a truly worldwide phenomenon.
