CACI, which stands for Catholic Alumni Clubs International, is an association of local Catholic Alumni Clubs located throughout the United States. They provide a platform for Catholic singles to connect and engage in various activities, making it easier for them to meet like-minded individuals and form meaningful relationships. CACI's mission is to encourage the development of local CACs, facilitate communication between these clubs, represent the interests of single Catholics on a national level, and organize their annual National Convention.

Each CAC offers a wide range of events and opportunities for its members, including social gatherings, games parties, fine dining experiences, spiritual discussions, and community volunteering. With CACI, Catholic singles can enjoy new experiences, meet new people, and make lasting friendships in a friendly and supportive environment
