Interact is Rotary International's service club for young people aged 12 to 18. Interact clubs are generally sponsored by a Rotary club or clubs, which provide support and guidance, but they are self-governing and self-supporting.

Each year, an Interact club completes at least two community service projects, one of which features international understanding and goodwill. Interact helps students develop leadership skills and personal integrity, demonstrate helpfulness and respect for others, understand the value of individual responsibility and hard work and advances international understanding and world peace. 

Interact is one of the most significant and fastest growing programs in Rotary, with more than 10,700 clubs in 109 countries and geographical areas, and with more than 200,000 members.
