The auxiliary organizations of the California Junior Chamber International (CA JCI) work to support the organization, its mission, and its members. They include the CA JCI Ambassadors, CA JCI Senate, CA JCI Order of the Tigers, and CA JCI Foundation.

Each is generally made up of veteran current and former Jaycees who have a great deal of experience in the organization and have proven themselves to be exceptional leaders. Each auxiliary organization focuses on one or two key areas and each sets it own tone and direction.

While separate from the main Jaycee organization, the auxiliary organizations run in tandem with the Jaycees and Jaycee membership is a prerequisite for involvement. The auxiliary organizations provide support and assistance to the International, National, State, and local Jaycee organizations. Their counsel is often invaluable and support is gratefully appreciated.
